Dude #1: What're you even talking about?
Dude #2: The thing with Cheryl.
Dude #1: What's wrong with you? That was this morning! Get over it, already!

Dude #1: The asshole who shoved past us on the escalator.
Dude #2: Oh...I didn't notice.
Dude #1: See? That kind of thing, that's what Cheryl was talking about. She has a point, you know.
