Funny, you don’t look fine

I took my wife to the eye doctor the other day.  While I waited for her in the lobby an older gentleman, sitting in an electric scooter chair, was called in by the doctor.  The man was a Vietnam Vet.  He was wearing a white cotton glove on his left hand, obviously to protect some kind of skin problem.  He had an oxygen tank strapped to the back of his chair.  The tank had a tube running to his nose.  He wore fairly thick glasses.  He was way overweight.  He was wheezing.  And when he talked his voice sounded like gravel.  The doctor said: “How you doin’ sir?”  He answered: “Just fine.” And drove his scooter in through the door.  Just fine?  Wow.
