there is a middle-aged gentleman who habitually smokes in the covered carpark. i know, because i see him when i walk E. there is a
prohibition on smoking in such a place. i have a natural desire to avoid conflict. so do most people.
today i decide not to avoid conflict. i call out to him, hi! i do not think you are allowed to smoke here!
he completely ignores me. i say louder, hi! you are not allowed to smoke here, you know!
when he ignores again, i walk up to him and say, hello, do you know that you are not supposed to smoke here?
and because he is unable to ignore me any longer, he says, mind your own business.
sir, it is because everybody minds their own business that smokers flout the ban with impunity.
also, a man should not get to middle-age and not have learnt how to respond civilly. mind your own business is uncouth and juvenile and shows a lack of vocabulary and intellect.
