NO 1 The theme of friendship in
the plot of the novel can
be linked to the great
relationship between
pokuwaa and her husband
in one hand and the friendship that existed
between pokuwaa and her
childhood friend Koramoa.
The friendship helped the
development of the plot
and the friendship also help the successful arrival of
pokuwaa at the end of the
pla to get pregnant.
Pokuwaa kept a good
relationship with many
people in the play, her friend Koramoa continue to
be with her friend Pokuwaa
after she herself has
successfully had her own
fruits of the womb. She
continues to encourage pokuwaa and helps her to
get through her ordeal.
The friendship with
Koramoa is a source of
energy, hope and strength
to pokuwaa. Also the friendship that pokuwaa
keeps with other character
is also a good source of
strength which sees to the
success of Pokuwaa at the
end of the plot. (2) The relationship btw
Pokumar’s mother and her
sons – in – law is not
cordial due to the
barrenness experienced by
pokuwar who is her daughter. Due to
maturilineal nature of
ghannians culture, it
behaves a woman to bear a
child in order to lay claim
of its custody. Pokuwa married two
different husband before
the third one which we
experience the plot directly
from the novel through
flashback, pokuwa recount how she divorce th first
two husband as her mother
was instrumental to her
action. Notably its the second
marriage with kwaku for
you who she left due to a trivial issue. Apparently her
mother advice her into it.
The essence, pokuwa’s mother
chaperon her in her
marital experience which
becomes fruitless. (5)
The use conch as a symbol
of authority and
rule of law is conspicous
for the democratic
process on the island.The conch is founded
by the intellectual
character(piggy)who
identified and trains Ralph
on its use.The hold
of the symbol is an authority in the first
assembly. It witnesses the
electron of Ralph
as the elected head of the
boys on the
island.Thus,it symbolises the emergence of
democracy and rule of law
to thrive.Also,in
the second assembly it
behooves every
participant to hold on to it as a symbol of
authority and orderliness
to contributes to
discourse on survival on
the island. 8

[story] Love in naija
episode 4 We kissed like starved animals,
and I heard his muffled voice
from cloud 9. “Cassandra, I want
to be a
better man” He drank of my
mouth like I was going out of fashion, his right
palm pressed against my
puckering nipple, just then I
heard my mother’s shocked
gasp. I turned to see her
standing with Mirabel behind us. The looks on their faces were
priceless, my mum’s voice
dripped rage.
“Cassandra I think we should
leave now.” Muna let go of me
instantly, looking like a little boy who was
caught stealing biscuits, he
mumbled an apology and went
after Mirabel who grabbed the
hem of her gown and stomped
out. My Mum’s face was burning with anger and mine with shame.
She held my elbow and guided
me towards the exit where our
car was packed. I felt like a
petulant child, why did I allow
myself to be caught in Muna’s scandalous mess? When we got
into the car, Mum
drove off without a word. You
could actually slice the tension in
the car with a table knife; I
couldn’t take the cold silence much longer. “Mum, I know I blew
it back
there, look I’m sorry” “You
blew it? You blew it?
Heeeehh!! Oh yeah you blew it
alright. Mirabel is one of my most ardent insanely rich clients;
didn’t you see him with her?
Was there no other male there
that you could lock tongues
with? Haba Cassandra, Nsi do
enyem?” I felt so bad, I had just found my
Mum and I didn’t want some
two timing, scheming sonofabitch
to come between us. “Mum that
was the guy that
helped me from the airport, the one that dropped the note at
the reception. I’m sorry, there
was already something between
us and the rest just happened.”
My Mum’s shock showed on her
face and her mouth framed just one word. “Oh” Then her
simmering rage
overflowed, I could believe that
my perfect mother had gone
gangster. “Oloshi, God will punish
that two timing bastard, heeehh!! Can you
imagine the fool? So its my
daughter that he is forming Jack
and Rose for Titanic? Listen to
me Cassandra, forget that
stupid boy, there are lots of them in this Abuja, he doesn’t
deserve you. Hah! Imagine the
guts” My eyes were as round as
saucers, my prim and proper
Mum was ghetto. Seemed every
Nigerian had street credibility, even the very polished ones. It
was so exciting, seeing my Mum
all claws. I couldn’t help imaging
her dig them into my step Mum. I
mentally jotted down not to tick
my Mum the wrong way. We got home and watched her
favorite soap opera together
and talked more about Muna.
Mum had calmed down but was
still acidic with her tongue. My
mind was made up. No more Muna in my life.
************************************
I looked at my completely made
over look in the mirror and
sighed with satisfaction. I had
been massaged, exfoliated, manicured etc. and my fair skin
glowed. I had on a clinging tiny
black dress that accentuated my
waist and round hips, Funmi had
invited me to ‘Club vanity’ in
the heart of the city. My first time of exploring the Abuja night
life but she warned me that she
would likely stop over at other
clubs before the night was over.
Funmi was my Mum’s
dermatologist and a typical Naija girl. She was tall with big bones,
with big hair, big laugh and big
sassy personality. She was
aggressive and sarcastic,
constantly teasing everyone
around her; they seemed to like it though because they laughed
at all her jokes. Over there in
US, I would have branded her a
bully or bitch but here I had
shortage of friends anyway, so I
overlooked her overbearing attitude. Hopping clubs was
perfectly okay by me, I was
young, wild and free. I chuckled
in spite of myself, I
didn’t see myself as wild at all
but that was my own deeply rooted issue, no one had to
know. I teased and fluffed my
hair into unruly curls that
cascaded down my back. I had
long hair but this was artificially
enhanced in a way that was not obvious. I heard a light knock on
my door and opened it to admit
Funmi who was looking very
colorful and sophisticated. She
took one look at me and burst
into raucous laughter, then she tapped me playfully on my butt
and said “See this babe ooh,
you wan
try? who you wan go kill for club
today? Mehn you too badt!! You
hot no be small.” I was happy she approved and
we went downstairs to her
Honda CRV jeep. Funmi was a
crazy driver; it was like she was
constantly high on life. She
played her music too loud, sang along so vehemently that making
conversation with her was near
impossible except she stopped to
comment on the singer’s
flawless delivery. She was playing
from the album of some Nigerian highlife big deal, Flavour
N’abania. Who she claimed was
too badt. It seemed everything
was either badt or hot to her.
At the club, it was all sexiness,
debauchery and Naija dancehall music. Nigerian girls sure knew
how to dress. We found a table
and settled down to order some
drinks. Funmi rushed over to the
next table were some guys were
lounging idly; it seemed they were her friends because she
hugged them and dragged them
over to our table. They came
over with their drinks and
women and Funmi made the
introductions. “Guys meet Cassandra,
Madam’s daughter from USA.”
They were really nice and warm,
one of the guys she introduced
as Aliyu took the seat beside me.
He was the only one without a woman and was acting oddly
familiar. His voice was also
seductive; did all Nigerian guys
have seductive voices? He
whispered in my ear “My love
how are you finding Naija? I hope say Funmi dey take
care of my love for me ooh. Do
you want to bite something?
They have some small chops.”
Then he grabbed my hand and
pulled me to my feet. “My baby do you wanna
dance?” Everyone at the table
laughed
and I almost died with
embarrassment, why the hell
was this guy acting as if he was renting me for the night? A
complete stranger, he had said
he was a medical doctor, why
was he acting like a crude love-vendor?
I decided to let it pass, to try
and be nice at least to avoid spoiling Funmi’s night. I followed
him to the dance floor
and in no time, we were gyrating
to ‘Your waist’ by Inyanya
that saturated the atmosphere.
Aliyu dropped his hands to my waist and then in an unbelievable
moment squeezed and pressed
me to himself. I slapped him twice
and backed away, he was
shocked for a second before he
angrily twisted my arm, turning me around to face him. Funmi
came over and slapped him too.
That was when we saw the
punch that hit Aliyu from the
back; it sent him flying across
the room. It was Muna, his angry voice boomed over the music.
“Guy! If you ever lay your filthy
hand on my wife again, I will
castrate you. Na my wife be this,
you hear me?” Bouncers were
everywhere and ordered us to leave; Muna linked
his hand with mine and gently led
me outside to his car. Inside the
car, he took both of my hands
and looked into my eyes as he
said. “Babe, I’ve ended whatever it
was that was between me and
Mirabel or any other girl, yeah
there were lots of them. I had to
stalk you on face book, saved
your pictures and have been using them as my DP on
Blackberry; even though you
stayed angry with me. That sent
a strong message and
all the girls I was messing around
with majority of them deleted me from their contacts, nothing
else matters because I want to
be with you…” I pressed my lips
to his and
kissed him, I had suppressed this
hunger for days. Just then Mirabel walked up to
the car, she was looking very
young and elegant in jeans and
chiffon top, she glared at me
and turned toward Muna.
“Muna, can I see you for a moment in my car?” Muna held
me protectively and
made to close the car door but
Mirabel held it.” “This is
ridiculous Mirabel, we
talked about this. I told you I need to move on with my life, I
nor get time for all these drama
now.” He forced the door close
but the
window was still rolled down and
that was when it happened, a guy in a hooded sweatshirt
walked by. His two hands were
buried deep in his pocket; he
stopped briefly like he wanted to
intervene between Muna and
Mirabel. Suddenly his hand flew from his pocket like lightening, a
black pistol pointed and fired at
Muna ‘point blank’; then he
took to his heels. Muna swerved
and slumped in my arms. I
screamed as my heart exploded into a million fragments, I
pressed my hand to the rosette
of blood gushing from the gaping
wound on Muna neck.
When I looked up, Mirabel was
gone, so were the Nomadic looking Northerners who every
one called ‘Aboki’ who sold
roasted meat (suya) by the
roadside. Later someone said I
never
stopped screaming, begging Muna not to die that I loved him.
All I remember was trying to dial
my Mum’s number with my
iphone that was sticky and
slippery with Muna’s blood.
Blood was everywhere, on my face, hands, cloths, the metallic
taste of blood was in my mouth
