W: The doctor should be able to see you in a few minutes. I just need some information from you first. What seems to be the problem?
M: Well, as you can see. I’ve got a rash on my hands and arms. I think it might be some kind of allergic reaction. My roommate just got a new cat. Maybe I’m allergic to cats.
W: Hmm. Usually, allergies to animals don’t cause rashes on your hands.
M: Well, maybe I’m allergic to some kind of food, or…
W: When did you see your rash first develop?
M: On Monday. By Tuesday, it was worse, and on Tuesday night I could hardly sleep.
W: Tell me, have you been out in the woods lately?
M: Out in the woods? I went hiking Saturday. Why? I get it. You think my rash might be caused by poison ivy, right?
W: Well, it looks like that. The doctor can tell you for sure. Do you know if you came in contact with poison ivy?
M: No, because I have no idea what poison ivy looks like.
W: It grows in clusters of three leaves, and the leaves are waxy looking.
M: Well, if I do have poison ivy, what can the doctor do for me?
W: He can prescribe a lotion that will relieve the itching. But if I were you, I’d go to the library and look for some color photos of poison ivy, and try to avoid it the next time I go into the woods.
