When I was a kid, I rode the bus home. One day coming home my mom had to run and get something from the store (don't remember what.) So I was locked out until she came home. While I waited on my porch, with my dog, two men on bikes rode up. They told me they were bible sells men, and wanted to speak with my mother. I told them she wasn't home. They had no backpacks. They had no bags. They were both dressed in white button down shirts, tucked into their black slacks. They asked to come in, and tried coming up on my porch. My dog named George, (a mutt we adopted, had since I was 4) got up from behind me and growled. The bigger man tried to pet my dog. George nearly took a finger. The smaller man asked again, if they could come in. "My dog doesn't like you very much, I don't like you either. You can't come in, and my grandpa lives next door, and keeps a gun on him at all times. If George don't like you, grandpa will shoot you." They offered me some nervous "god bless you" s and got back on their bikes and rode down the road somewhat quickly. They were arrested for breaking and entering a day later at an old man's house :)
