This afternoon, I was walking home. A man walking in front of me set his empty coffee cup down on a brick wall alongside the sidewalk.
Since I knew there was a trash can about twenty feet ahead, I just grabbed it and headed for the trash can.
The man turned around, pointed to me, and shouted, "Good karma!" Then he pointed at himself and said, "Bad karma!" Then he darted across the street.
I rolled my eyes and tossed the lid, cup, and coffee sleeve into the appropriate receptacles and continued on my way.
