I agree w/ the current crop of coddling kids.

Hence I appreciate the "hippie" school that we sent my daughter to. There's not a lot of safety features at the school. If a kid wants to climb a tree and get on the shed, fine. You can climb up as high as you want, the only rule that you have to get down safely yourself. We use that at home too. Works surprisingly well.

The kids could also pretend to shoot each other. BUT ONLY if you asked the other kid if it was OK. Sounds silly but I find it a more cooperative mindset.
