W: I am exhausted. My new exercise class is so hard.
M: Your new exercise class?
W: Yeah. My new advanced exercise class.
M: Why advanced?
W: My instructor thought that the beginner’s class was too easy for me. So I took an advanced exercise class.
M: Ha-ha, too easy for you?
W: Don’t laugh. In the beginner’s class, they give you a chance to rest between exercises.
M: So?
W: The advanced class is nonstop.
M: A piece of cake. You see, I lift weights every morning for sixty minutes without stopping. No problem.
W: Listen, Richard, doing aerobics for an hour is a lot different than lifting, weights.
M: Yeah. Quite a bit different; I think aerobics is easy. I could work out in your class with no problem.
W: You are not going to be able to move after weight lifting and the aerobics class.
M: Are you kidding me? It’s going to be a piece of cake. You want to bet? I bet I can go one hour in your class tomorrow morning and not feel a thing.
W: The bet is--I win, and you cook dinner for the entire family, or you win, and 1 cook dinner for the entire family.
M: It’s a bet. When’s the next class?
W: Tomorrow morning at ten o’clock. Try it?
M: No problem. Tomorrow morning after lifting weights, I’ll try aerobics. It’s a snap. Tomorrow morning at ten o’clock.
W: OK. Call my instructor, Jack Davis, right before you go there. His number is 555-8844. Remember the advanced class starts at ten o’clock. It only takes eight minutes by bicycle to the aerobics class.
