W: Would you like to join the Olympic Volunteers’ League?
M: Am I crazy? (19) I just quitted the Students’ Counsel. I don’ want to be as busy as before. I’ve given up a big chance of getting scholarships for that.
W: No, joining it won’t take you much time. It only has activities on the weekends.

W: That’s also a good choice. But the Businessmen’s Club just hold some boring activities, you know, speeches, competitions...
