input question: W: Sure thing. What'll it be? M: A menu, please. W: We don't serve food - just the beers you see on the wall. M: All right. What about that one? It's German, right? W: Yeah, it is. Is that what you'd like? M: Sure, that'll do. But I'd like a cold one if you've got one. W: Sure thing, sweetie. That'll be $6.25. M: Say, you're kinda friendly, aren't you? W: I suppose it comes with the job. It pays to be nice to people, don't you think? M: I suppose it does. That's what my mother said to me anyway. Oh, wait. Wait a second. Oh, no. I can't believe this! W: What's wrong? M: I think I left my wallet somewhere. W: It's gotta be around here. Maybe on the floor? M: No. It's not there. I don't know where it could be.

input question: W: Why did the women have this treatment? M: I don't know. The book says they used to consider it an honor to be the wife of the chief. The women used to become so fat that they could not walk. They used to crawl on their hands and knees instead. W: How terrible! I'm sure they wouldn't live for many years. Those women used to suffer a lot because of that custom. I'm glad that they don't do it now. What was said before this conversation????
output answer:
M: This book says that in some parts of Africa, men used to think that very fat women were beautiful. Before a woman married the chief, his servants used to keep her in a special house. Then they fed her all through the day and night for weeks before the wedding.
