I would not take a favor from the therapist either. For me, it would be like selling a piece of my soul to the woman. I have found with long breaks, like 6-8 weeks, after the first week or so I don't really notice because I deliberately make a different routine. I fill in the slot with something else - a massage, an activity with friends, something equally as onerous as I find therapy (make the dental appointments for the time of the usual therapy for example).

On the other hand, taking the favor is not bad in a vacuum either. People do like to be generous and helpful (sometimes even therapists if one believes the reports) and if you generally believe the therapist you see - why would you choose this to not believe her over?
