Andy: Hi, Vince?

Vince: Yeah, hi, Andy!

Andy: Vince, can you play tennis with me?

Vince: Uh, when?

Andy: Today.

Vince: Uh, no, sorry, I can’t. I have to go to the doctor and study for a test today.

Andy: How about tomorrow?

Vince: Sorry, tomorrow I have to play soccer and I have a piano lesson.

Andy: Oh. Well, what are you doing the day after tomorrow?

Vince: I may have to look after my little sister.

Vince: I’m sorry, Andy. I’m really busy this week!
