I remembered something from high school—Nancy’s irrational fear of butterflies. She had once screamed so loudly in biology class at the sight of them that the principal came running. That memory gave me an idea for revenge. I found a company that would deliver 200 live butterflies for special events like weddings. I ordered them to be delivered to Nancy’s home the night after the wedding.When the butterflies were released,

Nancy was a mess—screaming and frantically trying to escape them. My brother, shocked, tried to calm her down, but she was terrified. I thought about the years I had spent in fear of her, dreading school every day. Now, she was the one who couldn’t escape her own nightmare.The next day, my brother called, furious. He accused me of traumatizing his wife. I reminded him how long I had suffered because of her, and how, unlike her, I had moved on. But Nancy hadn’t. I told him I had filmed the whole incident and might share it. After that, I never heard from her again.For the first time in years, I felt free.
