Problem: M: No, but I can't stand him anymore. He is the worst roommate I've ever had. He never cleans up after himself and he is always listening to loud music when I try to get some sleep. W: Why don't you have a heart-to-heart talk with him? M: I've tried, but it didn't work. Maybe you can talk to him. After all, you are his good friend. What was said before this conversation?

[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.
