Yesterday...
Caleb : Daddy, can I eat the sweet the please?
Daddy : But it's quite late already.
Caleb : But I want to eat the sweet please.
Daddy : How about we share half-half?
Caleb : Ok, next time I got two sweets, I keep one and I give one to you ok?
Daddy : (wah, outsmarted, try again) No, I mean your one sweet now, I eat half and you eat half.
Caleb : No... only when I got two sweets then I share one with you. Can I eat the sweet now please?
Daddy : (no choice) Ok.

Last night
Caleb : I found another sweet!
Daddy : You said you'll share with me if you got two right?
Caleb : Ok, you can have this one. Eat it now.
Daddy : No, it's too late already, I'll eat it tomorrow.

This morning
Caleb : Daddy, you haven't eaten your sweet yet.
Daddy : It's too early in the morning, I'll eat it later.
After a while...
Caleb : Daddy, if you don't eat your sweet, I'll eat it for you.
Daddy : ?!?! Ok, I'll eat it now.
Caleb : How about we share half-half?
Daddy : ?!?!?!?!
Mummy : grins grins
Daddy : (In view of long term gain) Ok!
