Yes, I have a photo of T and I together. We went for a walk outside during the summer and I asked if we could take a selfie together. She said yes without hesitation, and she took it. It's a really nice photo of both of us. I printed it on a regular sized paper.

Why did I want it? I suppose because I feel close to my T and I like her. It helps me to keep in mind that we have a real relationship even though it's a professional one.

I know that many Ts would think it's crossing a boundary to take a photo with a client, or that it's confusing because it's a friendly kind of thing. Did you discuss your reaction when your T said no? If not, it's probably a good idea to do so.
