how exactly

its a matter of choice (love) ever wonder that guy across the blocks u never tot u cud talk to all of a sudden u wanna see him talk to him hold him all the time its choice baby.emotions can be deceptive it comes naturally from the heart

Someone once said dat love's a neurochemical event,just a few nerves firing persistently in your brain.for me,i think there's an iota of truth in dat cos subconsciously, love is flexible.if you disagree,raise your hand if your are sophisticated and educated enough to be on this forum and your claim to be in love with a bricklayer.love,sincerely, is a useful illusion,a way d brain keeps destructive emotions in check d mental while we drool and act mugu.i guess it's d best high d brain can get other than drugs, so it becomes addicted to falling in love.ask drunkards and marijuana users

U knw u're inlove when u hav this irrational need to make a complete fool out of urself for the one u want
