Minding my own business in Jamaica

How I learned to mind my own business: I was walking past Ward 21 the other day & all the patients were outside shouting, '13....13....13.' The fence was too high to see over, but I saw a little gap in the fencing so I looked through to see what was going on AND somebody poked me in the eye with a stick!!! Then they all started shouting '14....14....14'...
