So I accused him of being a Hufflepuff.

I can't decide if this sort of thing is banter or flirting.

Choir member: You forgot the cream for the coffee! I'll forgive you this time, but next time you get 13 demerits!

Me: Five points from Ravenclaw!

Schroeder: I always thought of you more as a Slytherin.

Me: I am NOT a Slytherin.

Schroeder: Yup. I've seen the darkness. Slytherin.

Me: Don't make me hurt you.

Schroeder: See? (pointing) Slytherin!

Me: (pointing back) Hufflepuff!

And then we made faces of smug superiority at each other.

I'm really clueless, people. What is this?
