I have been curious ever since I have had a T.

Where is the line you do NOT cross when asking personal questions?
Either client to T, or even T to client. Of course T to client would have to ask a lot of personal questions, since its key to "getting personal" to getting help in therapy. But I'm just curious, have you ever asked something inappropriate or have you thought your T has to you, as a client? What happened, did you have to change T, did you loose trust or feel violated?

How personal is too personal in therapy?
