The problem is we basically have a generation that has no proper concept of the boundaries of right and wrong. Or socially acceptable behavior, because all behavior is acceptable now.
Oh please.. were you an only child or something?
Children will and do stupid things, always have, always will, no matter how “proper” their upbringing... a proper parent recognizes a teachable moment when it occurs.... so that it is less likely to happen again, but if you think for one minute that this is somehow a statement on society as a whole, you are reaching.
Yes, they shouldn’t have done it, but guess what, there isn’t an adult alive who grew up with siblings who can say they never did anything stupid to or with them.... Difference was there wasn’t videotape of them doing it back when they were kids.
