Teenagers all over the world have a lot of problems.First of all it is the wish to be independent and to decide everything themselves.They argue with parents about the way they look, study and spend free time.They think that they are full-grown enough to do what they want.Sometimes teenagers begin to drink alcohol, to smoke to show that they are adults.Teenagers don’t want to have duties but speak a lot about their rights.But many teenage problems finish when a child grows up.
