Oh, Yes I Am"

This seems to be a common response from Timothy lately. I am not fond of it and it gets of my nerves when I hear it.

The latest usage of said phrase was yesterday. Timothy wanted to sit on the counter and was going to go get his step stool to help in his efforts.

T - "I am going to sit on the counter". (Usually because it helps him reach something I purposely put out of reach.)
Me - "Oh no you're not!"
T - "Oh yes I am!" (insert sassy tone.)

I give him "the look" and say "Excuse me?" to which he says

"Oh sorry Mama, I thought I was a grown-up".

He was wearing my shoes when this occurred and I told him that wearing a grown-ups shoes does not make you a grown-up. Hard to be mad when he is so darn cute!
