Hi, I’m Nikki, and I have a story about how karma sometimes needs a little push. When I saw my ex-fiancé, Mark, at a fancy restaurant with another woman, I couldn’t resist turning an ordinary night out into a perfect opportunity for revenge.

Five years ago, Mark broke off our engagement, claiming I “wasn’t good enough” after his promotion. He wanted someone more refined. It hurt, but I moved on.

Fast forward to last Saturday: single and thriving at 35, I spotted Mark at a new restaurant. I seized the chance for a prank. I had a waiter send over a bottle of champagne with a note: “To Mark, who always settles for second best.” His face turned red, and his date looked puzzled.
