My T and I hug at the end of sessions. Every once in a while she'll forget to offer (I don't bring it up because I have troubles asking for that type of thing), and so we don't. But it's just forgetfulness, and it only rarely happens. Only once has she said she won't hug me because we were both sick with colds and we obviously didn't want to spread our germs to each other even more. I think if she was super sporadic about it, it would bother me, but I know that when she forgets, it's not because of anything I did.
