It is interesting. Some people are just so very sensitive. One can see it when you speak to them. What makes them amazing is that they are so in touch with subtleties. This sensitivity can often be a deficit. They are so self aware that it can make others uncomfortable. How sensitive is "too sensitive"?
I suppose too sensitive is when one would rather be alone than realize that many others are unintentionally insensitive. I really feel for such individuals. I wish that I could help them, but short of kind words and suggesting a good therapist there is not much that I can do for them.
