My eldest, 13, had started doing his Duke of Edinburgh with the Air Cadets. A few Saturdays ago, they were walking and following maps and the temperature was at least 30°C. They were supposed to be out for 6 hours but the map reader got lost and they were walking for 12 hours.
He's high functioning autistic but amazingly he held it together and didn't moan or break down. So proud of him, he was knackered and sun burnt at the end. To be honest, I was pissed at the air cadet people for letting it run for that long on such a hot day.
