I've always been curious why alot of Ts have a couch. My last T did not, but had these odd comfortable chairs set up in different parts of the room. I always choose the farthest away. My current T has a couch and two chairs on either side of the couch. I have always sat on the couch. But one thing I hate is sitting right where the last person sat because there is heat from their butt! I want to confuse T and sit in one of the chairs.
