you have someone in your basement, and you don't know who, but you're too scared to go in, so you feed them day after day, just to feel safe because after that someone in your basement was there, you never saw your parents again, you're not sure if that someone in the basement ate them, but you're still feeding the person food, just to feel safe and the basement door is locked with many chains to make sure they won't go out, today you hear the basement door knocked again loudly
