I guess the thing to do now is try to do more with your children, as much as you can. I took mine golfing, on the bike path, etc., after work and on weekends. I notice some parents around here try to do that, make things a family affair.
Too much tv and video games are not good for kids. They get a skewed view of the world from technology. They need to learn about the birds, trees, bees, rocks and flowers, the beautiful outdoors that nothing can simulate, not to mention fresh air is so good for you.
It bothers me that so many kids are growing up surrounded by plastic. I saw a schoolroom with all bright colors and plastic everywhere. I think mine was better with the wooden desks and mosaic fishpond in my kindergarten room (the latter is long gone).
I agree - I think kids need lots of contact with their parents and lots of real, simple, enjoyable things to do. Even playing a silly card game like "Go Fish" or "I Doubt It" is fun when the whole family is there doing it, yelling at each other, nudging or shoving (in the case of my kids) and laughing.
But I think we need a little more judicial protection from the monsters in our society. Nothing is ever going to totally prevent them from attempting to do their evil, as your son's experience shows, but at least they should be discouraged from it by being presented with the possibility of serious punishment (death). Now it seems like there's virtually no punishment.
