I am one of those who likes to avoid confrontation, so if I get honked at or yelled at I stew for a few minutes and do my best to calm myself. I have very few confrontations, so I don't have many problems. There are always those occasions though when I would like to blow up...
I just don't think it's worth it to lecture anyone as much as I might want to. People need to make their own decisions about life and as long as they don't kill or hurt me, I see little benefit in trying to explain things to them. If they aren't smart enough to understand that they are endangering my life, a lecture won't help much IMO...
