Wow, you are light-years ahead of me. I found some old pictures getting my Christmas decorations out. I looked at them over the break and very affected by them. I put 2 of them in my drawing folder in case I wanted to share them. I ended up sharing them, talking about one of them but withdrew from discussing the second one. My T talked a little bit about it. As I put them away, she asked if I missed my mother. I just said,"I don't really remember her very much." and killed the conversation. I'm not really sure what I feel... At least you can go there.

Sounds to me like you are developing a good connection with this T. I don't have a box per se but I think I use my drawings kind of like a letter box. Images come out, I put them in the folder, then my T takes them.
