Their Loss, My Gain
One time, my friends and I were playing with an old Ouija board we found. It started to say some pretty threatening things about my girlfriend, so we threw it away in a church dumpster. This was a bad idea. The next day that church was struck by lightning and burnt to the ground.
Oddly enough, after the fire, a bunch of my lost objects reappeared: television remotes, old wallets, and toys I thought were long gone. Story credit: Reddit / (NosDarkly)
