Ok I'm completely creeped out by a patient I had. They absolutely had to smoke. I found them in their bathroom with a cigarette, they promised not to do it again. I found them again a bit later in their bathroom (the whole room reeked and it was going out into the hallway too). I spoke with them a second time about getting a patch or something and they threatened me with talking to my boss about it.
So later they went completely the opposite way, telling everyone they met about how wonderful we all are and how they want to commend us to the universe, etc.
Finally, they started taking cell phone pics of each person who took care of them.
I documented everything in case it came up again in the future and went home, but it's bugging me.
