Even since I was 10 or so I would often come back to school on my own. Then let myself into our apartment. Eat some lunch, do homework, play until my parents came home in the evening. I was effectively often alone for about 4 or so hours.I wouldn't let my kid do it here in US. Not because I wouldn't trust them or think it is dangerous. But because I am afraid what neighbors, school, CPS would do.
In grade school, my sister and I and our friend would sometimes spend the entire day in the woods in the dead of winter. The real danger in this country isn't the criminal and the bogeyman. The real danger in this country is the evaporation of real community and a broken pseudo-society of mutual disdain suspicion. Who is your real community? If you had a pet, who could you ask to watch your pet for a week? Who would you ask to watch your kids for an afternoon for no payment? That's your real community. Large numbers of Americans have no real community at all.
But apparently you are never safe from neighbors with an agenda.
Because they are "neighbors" and you are not in real community with them.
