The other day when I was walking home an old man - in his mid-sixties - took the last cigarette out of its packet and dropped the packet on the ground at the exact moment I walked past him. I turned around for a second look and saw a rubbish-bin no more than three metres away from him.
I stopped, turned around, went back to him and bent down at his feet to pick up the cigarette packet from the wet gutter. I put it in the bin - giving him a frustrated look as I shook my head in disappointment.
"Oh... sorry," he said, acting as if it was an accident.
I said, "It's our planet, our world... you know?" and continued walking.
Maybe next time he will have different thoughts processing before polluting our beautiful planet. Maybe he'll even look for a bin.
