NARRATOR：

Now listen to part of a lecture in a sociology class on this topic.

MALE PROFESSOR：

Have you noticed how when a student gives a class presentation, they might dress just a little more formally than usual?

For example, if you usually wear jeans and a T-shirt to class, you might wear nicer pants and a nice shirt or sweater because, you know, you’re dressing up.

You want people to know—even before you begin speaking—that you take this presentation seriously, that you’ve come prepared, that you’re a responsible student, that you’ve got a good presentation for us…

you get the idea.

Or, here’s another example.

There was this one time where I knew I was going to be giving the, uh, president of the university a ride; it was to a meeting across town.

Anyway, the day before I was supposed to give him a ride, I…

I wasn’t even aware of doing this, but the day before I was supposed to give him a ride,

I took the trash out of the back seat and even had the car washed—

I suppose I was thinking in the back of my mind that, you know, if my car was neat and tidy, the president would think that I was, um, responsible, respectful….

And then, to top it off, when the president got in the car, I changed the radio to a classical station.

Now, I don’t even like classical music.

I guess I must have been thinking that classical music would seem more, um, sophisticated.
