Mind your own business

I was walking past the mental hospital the other day..
All the patients were shouting.. “13.. 13… 13…”

The fence was too high to see over, but I saw a little gap in the planks, so I looked through to see what was going on.
some idiot poked me in the eye with a stick, then they all started shouting.. “14.. 14… 14..”
