I expect I might get jealous except that I never see any other clients (and that goes for all the T's I've seen, I think I've run across the existence of probably half a dozen other clients of different Ts in all those years). I'm dead curious about other clients of T and would love to be on speaking terms with them, even to exchange notes on T.
I actually like it when a T mentions other clients because then I don't feel so suspicious that I'm the only one paying their mortgage
As for giving a card, I am humming and hahhing about doing that myself this year, I can never anticipate the protocol with therapists. I don't think my T goes in for card giving but I *think* he might accept one. Not sure about that and I'm not too keen on accidentally crossing a boundary that's going to slap me one in the mush. Hope if you do give your T a card, it is accepted with good grace
