The Hammering Man's Story

When my little cousin was around two or three years old, his bedroom window started to leak after a storm. His parents did their best to staunch the leak while they figured out who to call to come fix it. It stormed again the next night but just as quick as it started, the leak stopped. My aunt and uncle wondered aloud at why my little cousin had the answer. It was the hammering man. I always believed the story because my dad was so happy to finally be an uncle,. But died shortly after becoming one.
