How old are you??!!

Mr. Christopher is 2 going on 22. He also thinks he's the boss around here and is not happy when he realizes that I am! He is constantly telling Nicholas what he can and can't do. "It's OK, Nicholas, you can have a snack," Christopher says two seconds after I say no. Then I say, "No you can't, we are going to eat dinner." To which Christopher replies, "I don't care MOMMY! I said yes he can!" To which I roll my eyes, give Nicholas the go ahead and try it stare, and continue on my merry way. How did this kid get so smart??
