so my cousin decides to have a sleepover at my place, since we don't really get to see him that much as we live somewhat far apart (and possibly since his parents wanted a break from him), and as it's the middle of summer, we decide to have a waterfight; balloons, guns and all. it all goes perfectly, until we decided to add some make-believe to it.

being kids, we decided to play a game where one of us is a suppervillain/mad scientist/pirate/other generic bad guy, and the other is a generic hero character; in this game, the hero has to put the bad guy in jail, y'know, generic kid stuff. we play this game for about half and hour, switching roles, when my cousin decides that he needed a mask; since he didn't want to ruin any of his halloween masks, he decided to get an old cloth, poke some eyeholes in it, get a piece of string, cut some more holes, and make a mask; he became a pretty artsy kid. after some time preparing his mask, he comes back outside to continue playing this game; we fun shooting water at eachother, when i decide that i was going to get him with a big blast, a really big blast. 

so i grab the hose, pump it up, and start firing it at my cousin's face for a few seconds, and then he starts running; i turned off the hose, and then ran off to catch him; when i reach him, he seemed to be crying, not fake crying; real crying. i took off his mask, and he looked shocked, and he was trying to catch his breath, just like he had nearly drowned and was minutes away from death. we go in, tell my dad about what happened, and he explained to us that since i was spraying water onto a wet cloth on his face, i was restricting his breathing, and giving him the feeling that he was drowning...
