W: This food is terrible. I can’t even finish my dinner.
M: I know. You think with all the money we pay for room and board, the university could hire a better food service. Where are you headed next?
W: I’m going over to the student recreation center to play some bridge.
M: You are spending your time on a card game?
W: Not just any card game. It’s one of the most strategic there is.
M: So I’ve heard. Don’t you play with a partner?
W: Yeah. Four people play, two against the other two.
M: So you try to play in cooperation with your partner.
W: Actually, the cards of one of the four players are turned face up. That player is called the dummy.
M: I wouldn’t want to be called that. When you are the dummy what do you do while the cards are being played?
W: Anything you want. Sit there and study, shuffle another deck, get snacks for everyone. I like to stand behind my partner and watch.
M: You know. I’ve heard that bridge is habit funning. You should be careful not to play so much that you don’t get your studying done.
W: Don’t worry about me. I only play Thursdays after dinner, and sometimes when they need a fourth player. If you like, I could teach you.
M: Thanks. But I have a pretty heavy workload this semester. I have to spend my evenings studying. I don’t really know how to do it yet.
