APY,
I don’t think it is difficult to understand at all.
I know, and you know that there are parents who all they do is lambast the school and blame them for everything they ridicule everything the school suggests. They talk derogatorily about the hanhala.
They loudly proclaim their “deios kozvos”
And then they want to know why their children do not have success in school when all they do is fight anything the school is trying to teach. And they wonder why schools do not want to accept their children.
The parents will not show the most basic respect to the principals when they come for interviews. They walk in with demands.
DO you doubt that these parents ambush their children’s success? Who do you think are the real “baalei gaavah?
