He once had a negotiating counterpart who he felt had a need to dominate her immediate space.  She had to be in the right in order to minimize stress that could otherwise debilitate her.  She was willing to meet you at some periphery and interact with you out there, but don’t come uninvited into her space — you’d feel yourself a house servant.  He enjoyed her quite well out on the periphery, and kept himself from wanting more — so that, when walking down a long corridor to step up to microphones, he felt that each looked the other’s equal.
