1. Kim: How punctual are you?
Ann: Not very, I suppose. I'm often late for work. And you?
2. Kim: I try to come on time every day, for work or for my dates.
Ann: It's difficult for me to be on time in the mornings. That's probably because you go to sleep late at night.
3. Paul: Let's have lunch together on Monday.
Liz: All right! At what time?
Paul: 12:30. Just please be on time!
4. Tim: What are you talking about? I'm always on time.
Liz: If I'm late once in a while, I have my reasons. I might be late Monday mornings for work.
