I similarly walked to school myself when I was a child in the US (1980s.) We were also left home alone with the door locked while parents were at work/groceries (https://en.wikipedia.org/wiki/Latchkey_kid https://en.wikipedia.org/wiki/Latchkey_kid) Today, this would be illegal where we live. From what I understand, it would also be enforced and child-services would get involved. It is hard to get an answer on what the cut-off age is when kids can be left alone, we have not received an answer from any place we've asked. While I appreciate the spirit of the law, and while we're well off enough that we dont need to worry about things like this...I do feel kids are quite coddled these days.
