Making Plans: How about next Friday

Annie: Hey, I know this new restaurant near my office. Why don't we try it?
Martina: Yeah, that'd be great. For dinner?
Annie: Yeah.
Dan: That's a good idea.
Annie: How about next Wednesday?
Martina: Maybe. Let me see. I'm sorry I can't. I need to work late next Wednesday.
Annie: Are you free next Friday?
Martina: Hmm, possibly. Friday's fine. Dan?
Dan: Friday? Sure, I'd love to.
Annie: Great!
Dan: Hmm, can I bring Leo? You know, the guy I work with.
Annie: Leo? Yeah, great idea.
