Where does she hear this stuff?

My conversation with N this morning...

N: Mom, what are you doing?
Me: Getting ready for the day.
(I was putting on makeup)
N: Ahhh, your driving me crazy!
Me: what?
(in disbelief)
N: and your making my feet cold.
Me: your not making any sense, and you have socks on.
N: just hurry up.
