David's mother always says, "David, don't!" " "David stick out your tongue, standing in a chair trembling to reach the sugar pot; David came home covered in mud and left a string of black footprints on the carpet in the living room. David fell out of the bathtub, and the water flowed like a river; David ran into the street naked ... every page had his mother's words "David, no!" " "However, the essence of this book is behind: David played baseball in the room and broke the vase. This is a catastrophe. David was punished for sitting on a small stool in the corner and crying. So, his mother said to him, "Baby, come here." His mother gave him a warm hug and said to him, "David, be a good boy, I love you." A childhood prank story, ending with such a loving act, is so classic. When a child is naughty and sad again, his mother's arms will always be his warm harbor.
