When I was a kid, you took care of things on the playground after school. Whatever the outcome, you'd go home and get a spanking by your parents and bullying was no longer an issue.
You do understand that your experience may not be typical.....relevant in todays world....or even normal and healthy, right?
I suspect you don't.
Do you expect a 11 year old girl that is being cyber bullied to "take care of things on the playground"? I don't expect my daughter to have to resort to violence to solve anything.
A child may not be physically inclined, or even able, to defend him or herself, much less "take care of things". It could incite even more physical violence, and result in serious physical and emotional injury.
EDIT: Just to be fair, are you just saying what your own personal experience was, or are you trying to say that is how things should be handled today as well?
Just personal experience. We didn't have FB back then. We actually went outside to play. If someone was bullying/being bullied there might be a quick altercation, but nothing serious. There weren't even that many instances. We were all (for the most part) well behaved... we had to be, or else get the spanking/belt from the parents.
What I feel parents SHOULD do (today) is absolutely restrict internet access (outside of educational materials) and computer time to their kids, especially social media garbage. Set the rules and discipline. Better yet, participate in their outdoor activities and education.
