With extra cheese

Overheard on a somewhat recent and entirely rare outing to a concert at a bar:

Susan: (standing) I’m going to get a piece of pizza.

Rachel: Oh ... oh.

S:         Should I get you a slice?

R:         Yes. No. Yes. No, I’ll just have a bite of yours.

S:         Should I get you a slice?

R:         No. I just want a bite.

S:         Are you sure?

R:         Two bites.

S:         I’m getting you a slice.

R:         No, really, just two bites.

S:         (Sits.) Forget it. I’m not really hungry anyway.
