The first therapist I ever saw kept wanting me to bring my mother in to an appointment when my mother would come to visit. I thought this would be a disastrous situation and I never did.

The second therapist wanted me to bring in the partner I was breaking up with and so the partner wanted to go and we tried it twice. I think the therapist wanted to do both individual therapy and couple's therapy - we declined and I only saw her for about 3-4 months (she was famed for wanting to do that with everyone who hired her and had the same thing she told all the others I know that saw her= a lot of people I know revolved in and out of therapy with her). It was not as disastrous as it might have been, but it was not useful to either of us. We still laugh about it (no longer lovers but very close friends).
