Interesting. I have believed for a long time that people are born good or bad. There are people that are unkind and there are people that are kind. Genetics. Behaviour genetics.

I am old. I do get irritated these days. That's because I finally understood that people weren't doing things because there was some greater good - it was because they were self-interested, and I will not longer tolerate other people's self-interest at my expense.

Oh, I'm 70, shortly to be 71.
