Do you really need someone to point out what you learned?

> - touching dog poop to enter a "ninja" club

Dog poop is icky and kids will make other kids do anything, and they will do anything.

> - entering many private properties

A lot of private property is not very tightly secured.

> - climbing dangerously high trees

You can climb trees. Might save your life one day.

> - crossing quadruple railroad tracks with TGVs passing on them. > - putting my head next to a passing TGV (about 2 feet away), just to see how it feels and be scared

TGVs are fast and dangerous. Also said railroad tracks may not be adequately secured.

etc. What would you have learned if you had stayed indoors? Nothing.
