Coincidentally last session my T had a sandwich - so did I (T comes to my home) as I just got home from school and hadn't had time to eat yet. A sandwich doesn't bother me, but soup? That's.. unprofessional.

A previous T used to offer me food (chocolate, nuts, something like that) during EMDR sessions (when we were taking a break), after that had happened twice I brought something, session after that she did, etc. It felt nice.. camaraderie or something.
