What has happened?

M: You look depressed. What’re you eating?
W: Our dog. He’ s missing these three weeks.
M: Oh. I know how you feel. There’s not so much we can do about it. Why don’ t you put an ad in the paper?

W: What help do you need? I’ll try to help you.
M: I’m going to attend an international convention in Harbin for two weeks. I have no clothes for that cold climate. Since you have been to the Northeast of China, what kind of clothes do you think I should take along?
