My T anniversary is just around the same time as yours. It's only my first, though so I don't have any past experience to draw on. I don't plan to acknowledge it to T in any special way because that just doesn't seem to fit our relationship.

I did want to add this, though... Sometimes, if T has said or done something that is particularly helpful, I will thank him for that either in person or in a voicemail message. Just something simple like "Thanks for encouraging me to come in today. I'm feeling much better and it really helped a lot." Really that simple. T has commented that he likes to get those messages or appreciates it when I thank him because it makes him feel good to know that something he's doing is having an impact.

So, my suggestion is kind of boring, but why not write your T an old-fashioned thank-you note. You don't have to be nervous about saying anything to her face. You can just give it to her (on your way out the door if you want her to read it later). She will surely appreciate whatever you have to say and you don't have to worry about whether or not she likes your "present."

Congrats on your anniversay!
