Ok, before you progress, imagine a little square. This square is the playground. (big asphalt area)
Now put a tiny circle in the middle. This is a sewer drain manhole thing. The middle of the playground is a lower altitude than the rest.
Great.
So today it rained a lot, and a big puddle formed in the middle of the playground.
After school the first thing that came to people's minds was "PLAY" I imagine.
Lots of little kids were wading around in it (went up to above their ankles in the middle)
Now at first it just looked like a puddle with dirt and leaves and such. But then, I look inside the depths and I see the sewer drain.
Suddenly, realization: they're swimming in backed-up sewer water.
I told everyone but lots of them refused to stop. This one fat chick just shrugged and started hitting people with a ruler.
Some other kid cussed me out cause I was "telling him what he can and can't do".
Discuss my school's stupidity.
