Tall Guy: What are you doing tomorrow night?

Me: Oh, I have this thing.

Tall Guy: Thing?

Me: Like, a meeting thing.

Tall Guy: For work?

Me: No, it's uh, for this other thing I do.

Tall Guy: Oh? What do you do?

Me: I'm uh, an emergency room volunteer at [insert hospital name here]. Like, domestic violence and rape crisis and stuff.

Tall Guy: …

Tall Guy: …

Tall Guy: Whoa.
