I think different Ts have different theories about this. I mean if they revealed a lot about themselves it would A. take time away from the client, B. expose the T to a lot of feelings and more of a friendship than a client-T relationship, C. it could potentially open them up for clients that could stalk them or whatever. I know some Ts will disclose a lot.... mine told me all about her and her husband and son and brought in pictures from time to time and when she was going on vacation would tell me where she was going. I know where she's from and where her husband is from and all about her son and daycare and her pets, etc. But I do know with many, many Ts that they don't share any personal info with anyone because they don't want to open themselves up and they don't want to feel vulnerable. They like a clear separation between the therapist and the client. There's not a right and wrong, but I agree with basically everyone else that I prefer the T who will share some of their personal life with the client. If I didnt want that personal connection then I would hire a robot to sit and smile at me. That being said, I do respect the fact tht some Ts do not want to open themselves up like that. It's just not a T I would be able to work with long term.
