Thank you all for such intriguing answers. I'm sorry that a couple of you have had such rotten experiences with therapists. I've certainly had my share, and it's messed up, alright.

I don't recall ever having lied to a therapist; on the contrary, I go the extra mile to be as truthful as possible. But right now she and I have been discussing a situation about a former romantic relationship...there's something I think I'm going to lie about. It's about a pregnancy that happened long ago. Very, very sadly it didn't work out, in terms of loss. At the time, I wasn't sure which man, of two, was the father. I am not comfortable with going into that whole situation with my therapist. I'm feeling like a simple "I'm sure the father was" so-and-so would simplify things.
