I think it's hard for us to know. It does sound quite cute. It makes me smile. I wonder if the important thing is not whether or not she did it, or whether or not it was appropriate, but rather, what did it mean? If you struggle with it, talking with her about what did it mean, and for her to talk to her supervisor about what it meant for her if she needs to.

Assuming for the moment that your Ts question about whether it was appropriate are well-founded as some suggest, and was not an act of kindness or therapy... well, Ts make mistakes all the time. Even good Ts make mistakes. And good Ts sometimes cross boundaries (and I'm not saying this was a boundary that shouldn't be crossed. I don't know. It sounds like it might be just a very cute story). My experience is that the important thing when something confusing happens is to talk about it. Did it help you feel more grounded? safe? or did it feed a dependence in you? (those aren't the only options. Just trying to give polar opposite examples) And if it didn't confuse you, and there isn't an unhealthy dependence, I'm not sure there's a problem - No Harm, No Foul.
