And that’s when I saw it.A thin, jagged crack in one of the old gas lines, just barely visible behind the shelf. I could hear it then—an almost imperceptible hiss.We called the gas company immediately. The worker who came out told us we were lucky. That smell—the “rotten egg” odor—was an artificial chemical added to natural gas as a warning sign. He said if we hadn’t found it when we did, things could have turned out much worse.After the repair, the smell vanished. Just like that.To this day, I don’t know if it was coincidence, or if my grandfather truly came to me in that dream. All I know is, whenever I smell something strange in my house now, I never ignore it.
