I'm very aware that many people have strong boundaries in regards to touch. Being that I don't generally understand these boundaries, I am very careful to keep from crossing them. I've been told that I am good about seeking permission for touch (incl. hugs) even from people that I've known a long time. This has actually given me the impetus to find a comment made by vamp_ire and put it on my userinfo page here. So, yes, I know that some people don't like touch and I -do- ask before touching.
The way things are going at work, I'm going to post this and get to the second part in another message.
