When I get nervous, I go to the library and hang around. The libraries are filled with people who are nervous. You can blend in with them there. You're bound to see someone more nervous than you are in a library. Sometimes the librarians themselves are more nervous than you are. I'll probably be a librarian for that reason. Then if I'm nervous on the job, it won't show. I'll just stamp books and look things up for people and run back and forth to the staff room sneaking smokes until I get hold of myself. A library is a great place to hid.
