Mike: Do you have to go home tonight?
Phoebe: No, I think I could come over. It's Saturday, right?
Mike: Oh.
Phoebe: What?
Mike: I can't do anything tonight.
Phoebe: Why not?
Mike: I have a date.
Phoebe: You have a date? With who?
Mike: Oh, it's my girlfriend.
Phoebe: You have a girlfriend?
Mike: Yeah. Well, when you and I broke up, I started seeing someone.
Phoebe: Well, for how long?
Mike: Three months.
Phoebe: Three months? Okay. This is probably none of my business, but how long are you gonna keep seeing her?
