Way back, I knew a psychic lady who would be in her 90s now if she is still alive. But way back in the early twentieth century, when she was a little girl, there was a flu-epidemic. And she got a nursing hat, went out and helped neighbors feel better. She got spanked very hard for that. That creates frustration.
Frustration turns to anger, and anger turns to violence.
I said yes. I said yes. We get a lot of reports like that. The teachers report to us that on the playground, the kids are helping each other when they get hurt. Not it's entered the classroom.
