What conclusion can we draw about Mike before he went to the camping school?

M: My brother Mike is just on a course at the Green-park camping school.
W: Really? What made him decide to do that?
M: Well, for one thing, some boys in his class decided to do it and they dared him to go listen.
W: You mean he really didn’t want to go?
M: I think he wanted to go, but I think he was also a little frightened. Of course, now that he has done it, he is very pleased with himself. He’s always talking about it.
W: So he enjoyed it, didn’t he?
M: Not exactly. I think he’s enjoying the feeling of having done it more than he actually enjoyed doing it.
W: What sorts of things did he do?
M: Em, all sorts of opening-air activities: hiking, camping, and canoeing. One thing he had to do was to capsize a canoe and then ride it again without getting out. He said the water was very cold, but he hardly noticed it at the time.
W: Why not?
M: He was busy riding the canoe.
W: That doesn’t sound very comfortable at this time of the year.
M: That’s what I said when he told me. On another occasion, he had to spend the day and night by himself in the open country.
W: Was he frightened?
M: He was at first, apparently. But then he got used to it.
W: It seems to me that the course did him a lot of good. I expect it made him more self-reliant.
M: That’s what he says. And now, he wants me to go.
