My grandma played a game with the author through a story about (Old Eurasian Pillow). The author always thought that a crow had taken (Old Eurasian Pillow) away. Later, when I grew up, I discovered that it was grandma and the author who played it. It was a joke that grandma took away (the old pillow).

Original text:

When I was a child, my family lived in a small town north of Laohetan. The town is built on the mountain, and the houses on top and bottom look like floors from a distance. The happiest thing I remember was when my grandmother took me to pick up "Old Bird Pillows" on the river beach. "Old bird" is a crow. The "Old Bird Pillow" is actually a small stone, about two inches long, cylindrical, and very smooth. Why is it called "Old Bird Pillow"? Does the old bird sleep too? I asked my grandmother more than once.

She also took the trouble to tell me: "People want to sleep, and old birds also need to sleep. When people sleep, they need pillows, and old birds also need pillows to sleep!" From then on, I believed my grandmother's words, every time When I came to the river beach, I picked up the "Old Bird Pillow" very carefully, and every time I picked up two full pockets.

It’s strange to say that the “old pillow” placed on the windowsill is really missing one! Grandma looked at me and smiled, and the whole family looked at her and smiled. Later, when I grew up, I learned that "Old Eurasian Pillow" was a game that my grandmother and I played together. The game was like an interesting fairy tale, and my grandmother and I were both important characters. Even today, whenever I pick up a small smooth stone, I will tell others with great interest: "Look, this is the 'Old Bird Pillow'."
