B, ask A why he/she wants to move out.

Why? Is your roommate really that hard to live with?

A, make your complaint.

I’m afraid so. He/she snores loudly, and it keeps me up all night!

B, ask A whether he/she has tried to solve the problem.

Well, isn’t there anything you can do about it? Have you talked to him/her?

A, express your disappointment.

I have, but he/she says there’s nothing he/she can do about it. I know it’s not his/her fault.

B, make your suggestion.

I think you can suggest he/she go to see a doctor. They can help people who snore.

A, make comments on B’s suggestion.

.Well, if he/she agrees, that would be a good idea. And I don’t have to move out.
