Oh so old...

me: Oh Evan...
E: Oh mommy...
me: I can't believe you're 4 years old!
E: I can't believe you're 100 years old!
me: You think I'm 100 years old?  How old do you think I am?
(Evan gives me a confused look...)
E: 35?
me: That's right!

Yup, when you're 4, being 35 and 100 are probably the same thing.
