Bam! Karma nails them. Over and over again. Painful, but mostly hilarious. The idea is that karma is like the universe balancing our actions out in a way, a scale of push and pull.
You hurt someone, something will come back to hurt you. Do something kind, and good things will come your way.
I remember getting an instant karma payback a long time ago. I was hiking, and out of my normal character I said something derogatory about my ex. Boom! I immediately trip over. Barely got the words out of my mouth. Lesson learned thank-you universe.
Do you think they learned their lesson?
