I'm not sure what category this question fits in. We camp as a family quite often and hike quite a bit. We occasionally camp with a couple of other families and different families have different styles of parenting and different expectations. Our boys 10 + 11 can go around the campground and depending on the area can hike short distances as long as they check in periodically. This past weekend our boys went with two other 10 year olds and took off for close to 2 hours. We were quite upset with our kids since they know our expectation is that they check in. The whole group tried to say they had no idea they were gone that long, and several parents were convinced that especially boys can really have no idea that 2 hours had passed. It is hard for me to believe. One hour perhaps maybe even slightly longer but is it possible that their brains could not register that length of time? We have been successful having them meet our expectation for checking in every 20-30 minutes, but it's usually not in a group of 4. I'm curious what peoples thoughts are.
