It's a natural behaviour for most species to spend their childhood and adolescence with their parents and when they mature enough, then they would leave them and live independently as young adults. Since humans are no exception, they also tend to leave to start living on their own. However, whether it is beneficial to take this action at an early age, for instance after graduation from school, has been debated. In my opinion, although it has certain negative effects, the advantages outweigh them.
