Cliff: Excuse me. I just had a sudden thought here. If you're not doing anything and you have the time, maybe we could go out sometime and do something together if you want.
Annette: Really? That sounds nice.
Cliff: Oh, well, I'd better warn you, though. I'm going on a special assignment for the department. I've got no right to ask you to wait for me.
Annette: Here's my phone number in case you make it.
Cliff: Great. Well, Auf Wiedersehen.
Annette: Bye.
