We rate everything else, so why not the hugs at the end of sessions? I have a scale with four steps:
H0 - This is basically the church-lady hug, where she turns her side to you so there's no real body-to body contact.
H1 - This is the "I'm not really into this" hug. It's front to front, but she limits it to cheek-to-cheek by arching her back so there's no real chest-to-chest contact.
H2 - This is a normal "real" hug, with chest pressed to chest. It's the one you get from people you love, and it's the basic man-to-woman contact that drives the world.
H3 - The real deluxe, sensual hug, often interpreted as, "can we get a room nearby?" I've only got one of these, but it was the most memorable hug of my life. I was in a class that lasted several months. It was a discussion-type class, where opinions differed radically. There was a woman in the class who was usually of the same or similar opinion I was, and we usually had each other's backs in arguments. The last day of class, we walked outside to say goodbye and her hug was not only chest to chest, but she pressed her thighs against mine. If she wasn't moving to another state to get married, I would have said that we definitely need to go out sometime, and probably soon.
After sessions, there are often hugs with the provider. What do you think about rating them along with physical attributes, etc.?
