there is a growing tendency that children mature at a younger age these days. our society should accept the reality and adjust the law accordingly.

　　today, the movies and internet around children have too many things about violence and sex. as a result, though we have tried all means to let children know only what they should know,children have known as much as adults. according to statistics,the underage crime rate is rising at a surprising speed. in addition, because laws in some places prohibit underage girls to have abortion without permissions from parents, the increasing number of unmarried mothers is also a worrying phenomenon.some surveys show that most 14 to 15 year old children think they are already grown ups, and are eager to behave in their own ways. but the adults' society doesn't think so. consequently, misunderstandings and quarrels between children and their parents and teachers have never stopped.

　　since we cannot change children, we can change our law.we should allow children over 15 to make decisions about their lives without the interference of their parents or teachers, and let them assume the responsibility for their own behaviors. maybe in this way, the world would be more peaceful.
