#Person2#: Oh, I see. Do you know what you are majoring in yet?
#Person1#: Not yet. I'm leaning towards business. But that's only if I can't get into computer science. How about you?
#Person2#: I want to go to medical school. So I'll probably end up majoring in biology.
#Person1#: That's cool.
#Person2#: Is the weather this bad all the time in the fall?
#Person1#: No, this is a typical autumn. It gets worse though, at least it's not raining that much. You'll get used to it. In the mean time, you'll have to watch a lot of movies. Seems like the only thing to do with the bad weather.
#Person2#: Oh, the professor is coming.
