I once had a patient who called me to the room to wipe his butt because he did not wipe his own butt at home....his wife did.

(I'm not kidding about this)
That same patient would call me to his room to pull the bedside table closer to him, and pour him a cup of cold water. He didn't have to do this for himself at home. His wife did it, or their "help" did it.
Was he too sick to wipe his own butt and get his own water? No. He was a walky-talky dressed in a silk robe and jammies who could do everything for himself if he wanted to. He didn't want to.
