I think there is always a price or exchange in every human interaction. As a very small child, there was exchange of sex to get attention and kind treatment from a family member. With everyone there is a "one can get x if one does y" exchange. With the therapist, they get paid x amount to sit and do what ever it is they do (I am still not certain they do anything but provide a very high rent space). I do not like it when the therapist seems to offer favors - example - I hate her couch and there are no chairs but the one she sits in. One day there was another chair in the office and she offered to move it - I turned her down - what was the cost of her doing that for me going to be?
I guess I don't see a problem with understanding all human interaction has a price.
