dialogue 2(informal)
So, what do you think we should do this weekend. What about going canoeing again?
Yeah, last time we went it was great! Oh, we should take our flashlights and explore that cave.
I'd rather not, thanks. I'd rather stay cozy and read my novel.
All right, oh, how about going to the circus.

Excuse me, Mrs Davis? Do you think I could speak to you?
Yes, dear.
Would you mind giving me and my schoolmate a lift to school? We need to see the headmaster.
Of course not. In about ten minutes, OK? We can go on the jeep.
Thanks a lot. That's very kind of you.
It's no trouble. Any time.

Hi, Christina. Have you got the blankets and sheets you borrowed?
Oh, I've forgotten them! I'm really sorry.
That's OK, bring them tomorrow. I need them for a campaign train.
Yes, I will, I promise.
