My T has a facebook. I added her and she declined. We talked about it later. She said it would break confidentiality. If someone saw me and then asked her "HEY! How do you know ____?" It'd be awkward. She said once I am officially a therapist it would be a bit different. We could know each other on a professional level and people wouldn't think twice about it.
Yeah I was bit a crushed. I have little ones who wanted to see pics of her and her little guy. But she is doing it for protection of me, and also to save awkwardness if people ask me how I know her...
