I love the back in the day posters. I have no quarrel with kids working, kids who grew up on farms pitching in, and the such, but you are ignoring a lot of things.
1. I didn't have a choice about spending weekends working on the family farm for free. A lot of you didn't have a choice. The kid in this story probably didn't have much of a choice but to get up on that roof.
2. For all the posters who fondly remember farm work as kids, how many of you have a friend or cousin who lost a finger, walks with a limp, or can't raise their arm above their shoulder? Know anyone that died? I have an uncle who lost an arm in a farming accident, and a good family friend died under a tractor after tipping it in a turn.
