'meimei' or 'didi'? (sister or brother)

yesterday night was a same boring night.. (coz I just recovered from cough and flu, so no char kueh tiaw, char kueh, keropok, no no no until I fully recovered! haiz)

I asked my agnes.. one question that suddenly across my mind...

me: tze tze, now you have 'didi' right. so what you want to have next? 'meimei' or 'didi'?

with smiley face.. tze tze starts to think and think... her both eye balls turning left and right..

tze tze: I want 'koko'.. *with BIG grin... (koko means elder brother)

Bappy and I laughed when hearing her funny answer.. never thought she will answer me 'out of box' one.. how to give her a koko har? hahahhaha!!!

me: err... *I don't know how to answer her back..

She doesn't have any elder cousin.. so I think she only can have her elder friends as 'koko' from her playschool.. :)
