I believe that parents should decide for teenagers spend their free time sensibly. right balance between learning and playing. First, young people can play thirty minutes in their free time after school is finished. during work breaks, teens can play sports such as basketball, football, badminton and so on. have few friends, free time is not known, then on Facebook all day. it's a waste of time. Second, young people can read books to develop the brain and thinking ability. Third, young people can help their parents with housework in your spare time, or go charity with her parents. Fourth, parents should provide for youth participation in social activities so that they are more confident and make friends. for this reason, parents should let teens participate in activities or play in their free time and do not create pressure for teens.
