(((((((((( echoes )))))))))) what an interesting thread.
After reading on PC about hugs I finally got up my nerve to just ask my T if I could have one and she said "of course".

Now she is sure to give me one as I leave, & I don't ask any more. Sometimes she even says,
I need to give you your hug before we go out there. Yes there are sessions when I feel too worthless to accept one, but that's another story.
I don't know how she feels about it (don't want to go there), but for me that hug is a momentary chance to vividly experience the gratitude I feel for her guidance. At same time I feel powerless to convey this, but I usually will tell her "God bless you". With your thread I realize that not only was my Mom not huggy, she didn't like to be touched & often got angry if we children tried (these were all residuals from earlier traumas of her own). this has given me a lot to think about. thanks!!
