[A]: W: Can I ask you some questions about your vacation?

[Q]: W: Well, I didn't intend to in the first place. But when I was in university, there was a course on senses. The other senses seem to be more concrete somehow, but smell is so personal. I found it extremely interesting. M: Do you have any interesting information to give us about smells? W: Well, let's see. Did you know that it's harder to forget smells than to forget facts? There have been experiments where people could pick out a particular smell thirty days after smelling it for the first time. M: Really? So smells can bring back more memories than, say, music? W: That seems to be the case. M: That's interesting. So what's your favorite smell? W: Oh, I have lots of different ones. The smells of the sea reminds me of happy family holidays, and the smell of roses makes me think of my friend's house. Strangely enough, I like the smell of air craft fuel at airports. Then I know I am going to fly somewhere exciting. But it's the general smell of my garden in the rain that I really like the most. That means I am at home where I should be.

[A]: M: Dr Stone, how did you become an expert on smell?

[Q]: W: I'd like to. How about asking Jenny to go with us? M: Oh, no. She is busy with her dancing class. You know, there is a very big performance in just a week. W: Yes, you're right. It is really not good for her to learn dancing. Her leg hasn't completely recovered from that accident. M: But she doesn't think so. She is crazy about dancing. Will you take your camera with you tomorrow? W: I want to, but I lent it to Tom yesterday. Do you have one? M: No, but I know Mary has got one. Let's go and ask her if she'd like to join us. W: OK.
