Childish? Me?

What did you do that for?
Look what you did.
You split it - don't look at me like that!
That sad little face won't work this time
No! Stop it! That's not fair!
Na na I'm not looking
Can't see you so that look won't work
Nuh-uh, I'm not peeking!
Well maybe a little...
Not talking to you anyway
No I'm not, 'cos I'm mad at you
Not the face again!
Well maybe if you fetch me another I'll be friends again
What do you mean, you'll tell my Mum?
No no no don't do that, that's not fair!
You'll give me a bit of yours?
Ok, fine.
That's what I wanted anyway
Haha tricked you!
