Business
How I learned to miknd my own business:
I was walking past the mental hospital the other day, and all the patients were yelling "13...13...13..."
The fence was too high for me to see over but I saw a little gap in the planks, so I looked through to see what was going on.
Someone poked me in the eye with a stick and then they all started shouting "14... 14... 14..."!
