Believe me, a well placed phone call to the mom of a kid misbehaving in my neighborhood got results. I recall playing bike tag and one of us ran over the flowers of an elderly woman, the one she recognized was me, MY mom got the call. I was in HUGE trouble. I was not the one who trashed her flowers, but the others were too quick to be spotted. There were no fights that a half dozen mothers did not personally respond to. We owned homes there and our parents enforced a standard of rules that we had to abide. We did.
Teachers are impersonal beings and phone calls to a harried mother/father at work too busy to be home does not always go as far.
In our world we teach kids the 'values' of eating in the style of what liberals define as 'fashionable' (for that year) - and 'saving the world' by jumping up and down in place - oops, I meant by 'protesting' with little signs"....
We're earning the horror.
