A: Hello, I would like to speak with Ryan.
B: This is Ryan. How may I help you?
A: Ryan, this is Malia, and I am afraid that I am feeling a bit under the weather.
B: Do you know what the problem is?
A: I have a horrible rash from poison oak.
B: Have you had it a long time?
A: The doctor said that I probably have had it a few days.
B: Have you been using anything for it?
A: I bought some over-the-counter lotion, and I am taking an antihistamine.
B: That will probably take care of your symptoms. I’ll see you tomorrow.
