This. In one of the recent threads about an unsupportive T, I mentioned that I consider my T challenging me to be a supportive thing, because he's helping me to see other ways of looking at things or other ways to react to something. I think there are a lot of people who don't see it that way.

Mind you, when T challenges me, he's not saying, "Hey, Critter, that's stupid, you're wrong!" He just calmly helps me see alternatives. So he's both nice and supportive.
