My T's acted kindly and supportively because they are kind and supportive individuals. You know your therapist; don't let other people convince you they somehow know your therapist better than you.

While I'm sure there are some T's out there who act nice only because they are being paid, I'm not cynical enough to believe it is even most of them. A person would burn out in a profession where they lived in that kind of professional irony all the time.
