Dr. Grumpy: "This is Dr. Grumpy."
Dr. Nerve: "Hi, Ibee. I'm over at the hospital."
Dr. Grumpy: "What's up?"
Dr. Nerve: "Will you have time in the next week or two to talk about something on the phone?"
Dr. Grumpy: "I have time now. What's up?"
Dr. Nerve: "I'm busy. I'll call you back when I have time. Thanks."
He hung up.
