You are fortunate to have got this far without having an adverse reaction to someone !
I would not call myself anti-social, as I enjoy the company of people a great deal. I do find, however, that my view of folk tends to polarise. Particularly as I get older, I find that there are some that I just don't even want to tolerate. This may be a feature of age, and the desire not to waste any time on things that don't truly matter.
