Hey Gary. You are a funny man!
The caregivers would kick it off with a rude comment but I still always said thank you when they left. And I never said Doctors.
Just because the torturer isn't charging does not mean you have to be on your best behavior. Rudeness begets rudeness. Have you ever picked up a hurt animal out of the street to help it, only to have it attack you? I did twice. And they were my dogs who loved me unconditionally.

When I got out of ICU my roommate was a friend of Bill's. (Overheard his company) And I told him that I was now at step 1 again, because I had regressed to that point. And I did call my sponsor and did 2 & 3. Also you will see that I wrote that I still thanked God every morning and every night thru my pain.
I spent 2 tearful hours buying Thank You cards today. $43.00 is a lot of cards. One for each and every caregiver, nurse, station desk, doctor, reporter, hospital, business persons and cameraman. I kept a list from day 1.
My wife put a copy of "Living Sober" in my suitcase, which I never opened until the day I left.
Did I do good honey? Your reply sounded like it was written by Nurse Ratched in the movie "One Flew Over The Cuckoos Nest". LOL
I got to go because "IT'S MEDICATION TIME, MEDICATION TIME"! LOL
