Situation:
You've just had your gallbladder removed, thrown up several hundred times, coming out of anaesthesia, coming down from the morphine, attempting to move but being in too much pain to actually move to where you want to be, and plus the oxygen tubes and IV line is pulling or getting tangled, and then a visitor arrives and says 'ooooh are you ok?'.....
Very caring, but if I could have moved, I would have killed him.
