Very Well Put ^_^ Couldn't have said it better myself!
Emotions are hard to "keep in check" for certain clients, especially after an SP gives them an hour of bliss, and makes them feel as though they are the most interesting, and important people on the face of this planet. (Not to mention extra brain activity in the insula + increased seratonin...)
I guess that sometimes, good service comes at a cost -- and that cost may be budding emotions in the client or SP. It may be easier for an SP to keep those emotions "in check", because she has that objective reminder (X-amount of money = paid bills/savings/gas/rent/tuition etc.) to keep her "in check". A client may personalize the experience, and become intimate as to minimize the feeling that they are partaking in a "transaction" - and that is where things may get gray. (As Amazon_Woman said...)
I don't necessarily think that there is anything wrong with personalizing sessions with a client/vice-versa -- so long as they understand that I am a person outside of this business, and I may not feel inclined to completely share myself with them. (Not to say that I am fake, I just don't think that you need to know everything about me...) (As Amazon_Woman said; there are certain boundaries...)
(Make sense ?)
Anyway, Good Luck Roland51! I hope that all turns out well for you.^_^
