At the ripe old age of 14, I decided that I was old enough and man enough to go out on a two day drinking binge/party at a friend's house whose parents were on vacation. When I came stumbling home at the end of the second day, my parents had completely different views on the situation than I did. After a rather unpleasant night of heated discussion about it, I flopped down in bed. I woke up the next morning to a stack of fence planks, string, plumb bob, and a box of nails. My dad sat there and watched me for the next day and a half rebuilding the fence by hand.
I learned two things:
1. 14 isn't adult enough for that crap
2. Fences are not hard to build, even hung over 14 year olds can do it
