I mean maybe. If it's in a medical facility (like say at the dining hall for lunch) I could see how that is okay. I used to plan a biweekly walk (from the office down the street and back) with a doc of mine and it made me trust him a lot more as a person. I think having the therapist see me outside the office may have helped him see my anxiety in a public setting which may have helped.

Tread lightly though... I could see where lines could easily be crossed
