Kid humor

Arien runs in the house screaming "Mom, I think. I think. I think. I think." Since she tends to sorda studder I thought there was going to be more to this. So I say "O ya you think about what?"
She says "Augggh (clearly annoyed because she knows I don't understand and yes she act like a teenager already) I think."
Well stupid mom. She thinks don't you know that. lol
