Mary, would you like to come over tomorrow?
Er, tomorrow? I have a doctor's appointment in the afternoon.
When is that?
At 3, but I have to leave by 2:30 to get there on time. I guess I'll have to pass.
Well, maybe you could come next week some time.
Sure, give me a call, and we'll get together.

Hi, Mary, are you doing anything tomorrow?
At what time?
About 6, I am grilling burgers, I thought you and John might like to come over.
I love to, but I have to study for a test tomorrow night. Thanks for asking.
Maybe you could come over next time. Good luck on your test.
