Kids are bad

This situation is happening many times:

Kids like to bother other kids, or even adult people. They are mad, but what I hate about it is that they REALLY hate being bothered, to the extend they may want to fight adults.

When I think about this, I recall there are adults who act like these kids. It seems people are degrading.

How to answer these "bothering" attacks. In kids' case, it is to talk with their parents; In adults' case, is to talk with The Law, because God had chosen His filters. And if you choose your own answer, you may be acting against The Law.
