FFS Yog, not everything is black and white.
Yeah, kids obviously lack the knowledge and discipline and adults and thus are more prone to do stupid things. But hey, they learn at least.
I confess, I actually nicked my parent's credit card and used it to buy gralats on several occasions back in the day. In the end, I regret doing that and repaid them for it.
But parents can't retain control over their kids forever and they can't watch their every action either which is why its up to the kids to eventually recognize responsibility for their actions.
The least we can do is set them down the right path.
