This is what goes on in the minds of 4 year olds?

My son is four. Most of what I say to him probably sounds like Charlie Brown's school teacher. In fact, here is proof. A snippet of an actual conversation we had on the way to the (you guessed it) Ontario Science Center.

me: blah blah blah blah
my son: Are you talking to me?
me: Yes. Yes I am.
my son: That sounded like two rocket scientists talking backwards.
