What should you do about bad parenting?

[REFVA]

This is funny,

I have to tell a funny story that happened last night.

I did a championship AAU summer league game. On one side of the court I kept hearing 3 second, 3 seconds 3 seconds. I thought i was loosing my eyesight. Oddly enough at half time I had an opportunity to ask the parents who is yelling 3 seconds I shouldn't have asked but I needed to just to clear my head. A woman turns and said me. I explained what 3 seconds was. She replied thanks, and then she was honest to say. "this is the only call I know".

Which I tend to believe that 90% of the parents don't have a hell of beans knowledge of any rule of basketball.
