John, a little boy living next door to me, liked fast food very much. His parents was so busy that they had a little time to cook for him at home. So they often took him eat fast food. That's because John became overweight. My mother had always told his parents that too much fast food was harmful, and they ignored my mother's advices. Recently, the doctor warned him never to eat fast food any more after the poor boy has a physical examination. Her parents came to realize what a terribly mistake they had made. Now John's mother often comes to ask my mother for advice in how to make healthy food.
