when i was 16, i was a lifeguard at the local college. the first weekend i worked, i alone had to supervise 50 or so high school boys who were there for a football camp. not a single one of them swam in the pool. all they did was belly flops. too timid, to ask them to stop, i let them talk me into judging the contest.
this, obviously, was crazily stupid not crazily fun or exciting. for, not only were most of these boys twice my size, but it turns out i didn't really know all that much about first aid or CPR.
