On another occasion, some years earlier, when I lived on Bay Street, I was leaving a corner grocery store on Bay and Gladstone with a bottle of Dr. Pepper. Outside on the sidewalk stood a transvestite who called after me "nice ass." I turned, smiled and pointed to the bottle of Dr. Pepper, saying "yes, but unfortunately, this is my only vice," before continuing on my way home.
Then, late one night on another occasion as I was walking home to my house on Bay Street, a man driving a compact car drove up alongside me and asked "are you looking for something?" I retorted sternly "I beg your pardon," and he said "never mind" and drove off.
The moral of this post is when you are out in public you will come across people who make indecent proposals. If you are sure of yourself, either ignore them or just say "no thank-you" and get on with your day.
