I know 74 but listening to the thoughts he has shared helps me to understand the nature of some that we might be up against.
You can otherwise blame my mother. She never tolerated her kids being impolite or mean to anyone. We were poor but well-behaved and respectful. I was always the one who was nice to the kids that others unfairly picked on at school (the fat kid, the not so bright kid, the nerdy kid etc). All that said, come SHTF, working with my neighbors, I will dispatch rogue assassins that threaten me and mine.
