One sunny day, my son was reading a book outside the door. It's time for dinner, but his son is gone. The father went out to look for his son, just calling his son who was immersed in the sea of books to eat. He looked at it himself. His mother found that his father didn't come back. His son had to go out to call his father again and found his father lying on the ground reading a book, which made him laugh and cry!
