I don't think all teachers, bosses, or Ts care. I think the good ones do, though. And just like with any other person, I think you have to evaluate what each one says and decide if you believe it, based on your experience with that person. But I think they can all care very deeply about the people they work with, and though it's not the same as a physically intimate relationship, it is an emotionally intimate one and that is very powerful, maybe even more so.
