Aidan has a "type"

I just walked in the door from picking Aidan up at the airport. He flew unaccompanied as he so often does lately. Driving home, I asked him about his flight and the following conversation ensued:

Me: Were you the only unaccompanied minor?

Aidan: No, there was one other kid.

Me: Boy or girl?

Aidan: Girl.

Me: Was she cute?

Aidan: She wasn't really my type.

Me: What's your type?

Aidan: I prefer blondes.

Just turned nine

I'm in so much trouble.
