We have a summer cottage in a community of several hundred other cottages. When I was a kid, I was allowed to run around and play with my friends, but once in a while my grandmother would go out on the porch and yell my name really loudly, and I had to come running back to "check in". If I was too far away to hear, I risked getting into trouble. One day when we were both 13 or 14, me and my friend took our heavy one-speeder bikes and not just outside the community, but along the highway all the way to the nearest town, which was 25km away. We bought ice-cream, looked around for a bit, then biked back. By some lucky chance, my grandma didn't even notice I was gone!
