This is interesting (and tough) question for me. Yes I would like my Therapist to be primarily my Therapist but that doesn't mean that if we happen to cross paths that we can associate and communicate with one another. Since my Therapist and I are both very young (Solid Gen Yers) we may (and I know that in a few cases we actually do) have many common interests, so Hypothetical Situation: we are both at the same music concert (let's assume it is an all GA venue) and we happen to run into each other at the show I would definitely like to speak to her and enjoy some of the show with her there. So to provide a somewhat clear answer- No I probably wouldn't want a full-on friendship with my Therapist (which even I think is sort of our of line) but if our outside paths happen to cross than we can definitely associate at the intersection (before once again going our separate ways)
