how long?!

the kid: mommy, I'm big. I'm really really big.
me: yes, you're really really big.
the kid: so I can go to kindergarten.
me: yep.
the kid: so when do I go to kindergarten?
me: after your birthday.
the kid: what?! that's a long time. I don't want to wait a long time! (pout)
me: you have to be 5 to go to kindergarten.
the kid: you didn't tell me that part, mommy. you should have told me that part.
