It wasn't the schools, nor was it their peers. It was us , their parents. We hate this obvious conclusion because then we'd all have to take some responsibility for what our children feel and do. We don't want that. We want to avoid feeling guilty, so we blame others and expect them to fix the problems we created.
Young children are much like puppies.
They need to be fed, given water, and protected from extremes of heat and cold. But like puppies, they also need something else. They need to be loved. Look what happened to my hypothetical dog when I gave him everything but my affection. Real Love is not affected when I'm inconvenienced or hurt by the person I love.
