A blue door

Every morning, a blue door appeared somewhere in town and disappeared at sunset. One day, Sara opened it. Behind the door was a room filled with glowing bottles. Each bottle contained a forgotten memory. Then Sara saw one with her name on it. Inside was a memory of her grandfather, who had passed away years ago. He was hiding a small box beneath an old tree. Sara ran to the tree and found the box. Inside was a note: “Some memories are forgotten for a reason. But the truth is always waiting.” Sara looked up at the sky, wondering what secret her grandfather had left behind.
