The good news is that this issue used to be (when I was in my 20's) like an 8 or 9 (out of 10), now it's like just something nagging in the background, and maybe as low as a 1 or 2.

Edit: Here's something else that's a little odd. In general, I tend to be so forgiving of these people, that I forget from one encounter to the next, that they tend to say these nasty things to me. So much so, that I'm continually surprised (even amused) by some people's bad behavior.
