Where can the two speakers probably be?

M: Can I help you?
W: My son is going to have his 16th birthday party at home. I’d like to get him a gift.
M: What price gift are you interested in? We’ll need to know that before we begin looking.
W: Well, I usually spend about twenty dollars on a gift. Do you have anything nice for that price?
M: How about a pen and a pencil-box?
W: No, my brother gave him that for his birthday last year.
M: Well, would he enjoy a book on how to play PC games?
W: No, he is good enough to write a book himself. He is a good player on PC games.
M: Then you can gel him this magic car. He must be interested in that.
W: Good idea. I’ll take it.
