"Hi, this is Mrs. Fried, and I need to make an appointment. Please call me back at 867-5309."
So Mary wrote down the number, and called the lady. No one answered, so she set it aside to try again later.
At 11:45, a little over 2 hours later, they called back. "Hi, this is Mrs. Fried again. My schedule is busy, so I don't think I'll be able to come in at all. Can you cancel the appointment that I haven't made?"
