Excuse Me, What?

This conversation happened between D and me this morning. Please note that she asked me to make her breakfast before this conversation took place.

D: Does it seem crazy to you how grown up I am?
Me: How what you are?
D: Grown up.

Me: Um.

D: .......

Me: When was the last time you made a grilled cheese by yourself?
D: At E's house. It took us like half an hour and we burned the first one.

Me: Yeah. So what were you asking me?
