the mom was not there when the son came in with the knife. when told about it she laughed, that lovable little scamp. She was not there when my friend unburdened himself about what he considered his obligations to the kid, and what he thought was the difficulties. At any rate, it's a long time ago now. I was just sharing it in that people for various reasons may end up shouting while trying to do their best, then again people may also end up shouting because they are too stressed by situations which is also a problem, but they should be helped then.
