Vivian: Let's call William and see how he is doing. It's important to follow up with him, in case his depression has worsened.

William: Hello?

Vivian: Hello, William, this is Vivian from the Hepatitis C Treatment Clinic. I am just calling to see how you are doing on the new dose of medication.

William: Thanks for calling. Actually, I am feeling better. I haven't been quite as sad lately

Vivian: Have you been irritable or tearful?

William: Well, maybe just a little, but overall, I am feeling a little better. I think it might be helping.

Vivian: That's great to hear! Let's hope your mood continues to improve. I'll see you next week when you come in for your check-up.
