Situation : two friends meet on a university campus.
A : You’re in a terrible hurry. What’s up?
B : I want to get to the bookstore before it closes. Doesn’t it close at 4:00?
A : No, 4:30.You’ve got lots of time. I’ll go with you. What is it you’re looking for?
B : I want a physics book that I can understand. I’m not making any progress at all no matter how much I study.
A : Have you spoken to the teacher?
B : Him? He can’t explain anything. When he tries to, he only makes it sound more difficult.
A : It doesn’t look as if you’re going to get a good grade.
B : I’m not worried about grades. I just hate sitting there not understanding anything.
A : Here we are. Look, the physics books are over there. Let’s go and have a look.
