When my brother announced his engagement, I was thrilled—until he said he was marrying Nancy, the girl who made my childhood miserable.At the engagement party, she hadn’t changed. Her insults were wrapped in fake sweetness, but I saw through them. “Still the same little loser,” she whispered,

I had a plan. Nancy had a deep fear of butterflies. So for her wedding gift, I arranged for 200 live butterflies to be delivered to her home—with instructions to open the box inside.Her screams that night were priceless. My furious brother called, but I simply said, “Oh, now she’s traumatized? That’s interesting.”That was the last time I heard from Nancy. And I finally slept like a baby.
