A: Hello, Nicole? This is Jimmy in 309.
B: Hello, Jimmy. What's up?
A: You're not going to believe this.
B: Believe me, I think I've heard everything.
A: I can't find my mailbox key.
B: Is that all? That's a lot better than losing your car keys.
A: I had a duplicate, but I can't find it either.
B: If you come by my place, I can loan you a key.
A: There's no emergency. All I get is junk mail and bills.
B: Can you wait till Wednesday? I'll make you two more keys.
A: Sure, that'll be fine.
B: Okay. I'll see you Wednesday. But it's going to cost you $2 per key.
