Sometimes it is necessary to tell someone bad news gently.
1.A： I'm afraid I spilled coffee on the tablecloth.
B： Oh， don't worry about it.
A： I want to apologize. Is there anything I can do?
B： Just forget about it. I never did like it anyway.
2.A： I'm really sorry，but I seem to have misplaced your scarf.
B： Oh，that's all right.
A： I'm very sorry. Can I get you another one?
B： No. Forget about it. It's not important.
3.A： I'm sorry，but I can't find the book you lent me.
B： That's OK.
A： I really feel bad about it. Let me buy you a new one.
B： No. Don't be silly. I wouldn't dream of letting you do that.
4.A： I feel terrible，but I've just broken your ashtray.
B： It's nothing to get upset about.
A： I don't know what to say. I'd like to replace it.
B： No. It's out of the question.
