hope there is no any sign of being disrespectful in cheerfully asking one's father how he met his mother?

Na its not disrespectful. I know how my parents met. Heard the story too many times sef.

If you have a close relationship with your dad, why not. Am very close to my mum and she told me how she met my dad

I dunno oh

never asked him.asked mum and she told me every...

No it's not bad. I enjoy the story.

If you have a good relationship with your parents, I don't see any reason you shouldn't. And how is it disrespectful?

I asked my dad when he was alive and he told me.
I asked when I was in primary 6.in the presence of mum.

And she fill it in when dad was omitting some details she feel we should know.

Gush!!!!!How I missed my childhood days in the name of growing up.
