had an elderly man in the hospital s/p bilat TKR (why do they always get confused when they have BOTH knees done, but not when they do them one at a time???!) This guy was so-o-o-o- confused, he thought he was at home, and we (the nurses) were home invaders. After he pulled my ponytail from the proper back of the head position, to the side of ,my head, I got steamed. "LOOK AROUND YOU!" I said, "DO YOU HAVE A ROOM IN YOUR HOUSE THAT LOOKS LIKE THIS???" The guy looks at me and says........"HAVEN'T YOU HEARD OF REDECORATING?"
