RE: Bad behavior at the grocery store.
It bothers me when I see things like that too. If the stores would at least attempt to hold the parents responsible to pay for what their children destroy, it "might" make them look after the children better later. Maybe not, but still. It IS unfair to businesses to have to lose those items. It's almost the same as shop lifting in a sense. Sure, they are not trying to take them home, but they have effectively made a loss for that store.
I frequently see unattended children, some very small, allowed to play in the toy sections in stores. They may not totally destroy anything, but now those toys are used. Some you may not be able to tell, but many you can. So sad that there are so many people who have zero respect.
....and like you said, then there is no wondering why, when the children grow up to do the same.
Good luck getting parents to be responsible for their own kids. Everyone these days seems as though they want the world to take care of them without them taking care of themselves.
It's definitely a difficult life, and I know kids make a harder, at the same time I know money people aren't ready for kids but they have them anyway.
That probably has to do with their parents not teaching them when they were kids you know but it's a weird world so what are you going to do.
