Curiosity...

I was walking past a home for the developmentally disabled the other day. The wall surrounding it is solid. All I could discern was a large group of residents shouting 13... 13... 13...!

The wall was too high to see over, but I saw a small hole a little below my eye level - kinda shoulder-height. I hunched a bit to see if I could get a good look at what was causing all the commotion.

Some fucker poked me in the eye with a stick. Then they all started shouting 14... 14... 14...!
