What can be inferred about the man?

M: I am really under the weather, I can’t tell up from down.
W: You’ve been sick quite a hit since you got here, haven’t you?
M: Well, for the past few weeks, the weather in this city has been changing a lot. It’s awful. One day it’s hot outside, and the next day it’s raining. No matter what I put on, I’m always dressed inappropriately for the day. Just last Monday, I wore a T-shirt and a pair of shorts, and we had a thunderstorm. I believe that day is the reason I’m sick now.
W: You just haven’t learned to predict the changing climate in this city yet. Many newcomers complain about the same problem. I’ve been here for five years and I rarely get sick because I’m always dressed appropriately for the weather. But when I first came, that was a different story. It takes a while to learn how to predict the weather for the day, but eventually you’ll learn.
M: I know. There’s just a period of time when I’m still learning that’s the hardest to get through. I guess I’ll just have to buy lots of cold medicine in the meantime.
W: I heard there’s a weather hot line that will tell you the temperature for the day. I’d like to find out if it really helps. Maybe you can give them a call tomorrow morning.
M: Not me! I heard that it was very expensive and I don’t have that kind of money.
