IThough there are many people want to lose weight,I want to put on weight.I am ten years old and my weight is about 20kg.The children around me all treat me as the small sister.I am already ten years old,but they treat me as a child.And sometimes I want to help my mother to clean the dishes,but she always rejects me because I too small to catch the desk.If I can put on some weight,everything will be different.
