Grandma took it. In the article "Old Man Pillow", my grandmother and I said when I was a child that an old man's pillow refers to a crow's pillow. People need pillows when they sleep, and crows also need them. Since then, I have picked up many old man's pillows every day and put them on the windowsill. Every day, when I wake up from sleep, I will find that there will be one less. It was not until I grew up that it turned out that my grandmother and I played games, which accompanied me throughout my childhood.
