- is it not obvious?

I was recently sick and had to see a doctor. When I was called in to see him, the nurse greeted me with: How are you doing?... I looked at her and said, well.. I feel really bad. She was confused, she was expending a good or great for an answer.

I noticed that they do that to everybody, but isn't it obvious? If you go to the doctor's office is not because you are well and happy. Right?
