M: I haven't seen you for a long time. Where have you been?
W: I went to New York to visit my sister and stayed there for two months. Actually, I really went to meet my new nephew.
M: That's great. How old is he?
W: Well, he was five months old when I got there. And he could possibly be the most beautiful baby I've ever seen.
M: What did you do in your sister's home?
W: I helped the baby and played with him a lot, which was nice. But what I enjoyed most was feeding him.

M: Air pollution is so bad in this city. I think the government should stop people from driving cars on certain days.
W: You have a point. Air pollution is a problem, but not letting people drive on certain days is a bad idea. People have to go to work by car.
M: I'm afraid I don't agree with you there. Air pollution is really important. People are so used to driving that they don't think of other ways to do things. If we stop them from driving on certain days, maybe they could think of new ways to get around.
W: I see your point. But I still think it wouldn't be possible to stop people from driving.
