in kindergarten, I naturally hated boys. And I used to tell my friends (who were all girls, of course) that if we dug a deep enough hole, we'd get to this magic kingdom where girls lorded over boys and we'd all be princesses. I really believed this, so for many a recess my buddies and I would be in the sand, digging a hole. The boys could not figure out why we kept digging, and we didn't tell them. We did get mad, however, when we'd come back out at recess and find that someone had filled our hole in!
