Sunset Horseshoe Box

The boy lived at the end of the valley and lay by the window every evening to watch the sunset. He firmly believed that the setting sun was a huge gold coin, and the small piece of afterglow in his hand was falling debris. So he collected "crumbs" every day and stored them in iron boxes. Many years later, he left the valley and traveled around the city, never seeing a sunset like that again. Until one evening, he dug out the rusty iron box - the "debris" collected in his childhood were just a few pieces of ordinary broken glass. He smiled and said out the window: "But at that time, they were really shining."
