I can't remember if T1 did that. Maybe she wished me happy Christmas if we had a session right before Christmas, but I'm not sure. Other holidays not. With easter we don't do anything, we just have some time off. We aren't religious.
Most years she hasn't even wished me a happy birthday.

Current groupT's do acknowldge it. Every groupmember even got a sort of Christmas card from them. I gave a small card to them. I wouldn't do that to T1. Don't have the guts. I did gave her a goodbye card when she went on leave, and she thanked me for it. But I won't do that sort anymore. I feel it doesn't really mean anything to her. It wouldn't care. And I won't get anything from her. Not that I want much. Just a card/note. But whatever, I'm nobody.
