It sounds like you've already made up your mind about what you want to do. You're going to get mixed feelings about giving T's gifts here. They are not a friend, no matter how much you like them or appreciate them. I've never personally had a T long enough to have a strong connection with them, therefore I've never felt the need to give anything as a gift.
Sometimes I bring my T stuff from work, but I always ask if she is interested first before I do.
I would say go with your gut, if you want to get you T a gift go ahead, but keep in mind it isn't meant to be that kind of relationship.
