That's a good definition, I think, RTS. I would add that if a person has your best interest at heart, but doesn't respect your own views of what that is, it would be difficult to trust them. For instance, suppose that you have a collection of something that is very important to you, and a relative believes that all possessions are evil clutter, so they sell it off on ebay "in your best interest". That wouldn't be a trustworthy person. So the person has to be able to see beyond their own opinions and world view - maybe that's why a good T is a better person to trust than most other people, at least in my experience. They are trained to be more broadminded than many other people. (Not all of them are broadminded, but they ought to be.)
