- I'd love to go to the rock festival. Are you going to come with me?
- yes, I'm certainly going to come.
- all right. We could put the same t-shirts on.
- oh, that would be nice. Can we take tickets on 10:00 pm?
- oh no, I'd like to go at that time, but my mom will not let me go. Can we go at 4:00 pm.
- sorry, I'm afraid I can't. I'll be at school at this time.
