A: How do I buy my textbooks?

B: Do you have your book list for your class?

A: Yes, I have my list.

B: Fine. Once you have it, you can go to the bookstore. Do you know where that is?

A: Yes, I know where the bookstore is.

B: OK, so once you pass the gym, it's the first door on your left. Do you know you can also sell your used textbooks there? 

A: No, I didn't know I could do that.

B: You just take them with you and trade them with the used textbook man just outside the door. Do you think you will be doing that today?

A: Yes, I am going today.

B: Well, if you decide to go, I could meet you over there at 1:00 today or tomorrow to help you. Would that work for you?

A: Yes, thank you. That would be great.

B: Well, then, I'll talk to you later. Have a good day!
