I have taken the view most of my life that people aren't jerks and generally speaking I've had a pretty stress free life. But I don't know which caused which.

However, now that I've past my half a century, I'm realising that there are more jerks than I had thought!

But there is a spectrum of jerkiness (for want of a better word for it) so now rather than getting wound up by the occasional confirmed jerk, I'm mildly irritated by jerky people in general.

On the plus side, I now know people probably think me a jerk whatever I do, so that's one thing I don't have to worry about any more. I'm think I'm comfortable with that.
