I grew up with 3 brothers (and of course, their friends).
Boys are always doing shit (and quite often, stupid shit) that involves bricks, sticks, ropes, matches, nasty smelly bayou water, etc.
It is quite a difference to how little girls play. There are three little girls who live a few houses down. They come pick flowers at my place then spend hours debating, talking, fighting, negotiating and crying about how best to arrange them.
