I put some gasoline in a small dixie cup because one of the neighborhood kids said it would sparkle when lit. I caught the gas can and the dixie cup on fire. Luckily, a neighbor quickly jumped the fence to smother the fire. Then it was Woodshed time.
Now that’s good luck your neighbor was around.
When I was an adult, two hoodlums in our neighborhood lit a fire in my backyard. I yelled at them, put out the fire, called their mom and told her what they did, and they got a pat on the back. I hated those neighbors. They weren’t even next door neighbors. They lived around the corner from us.
