In the past, young people only left home once they got married. Nowadays, though, youngsters tend to leave earlier.
Over the past few years, there has been an increasing trend of adolescents staying away from home and parents to another place for the purpose of getting a good qualification or employment.
Deciding on whether to stay with family until you get married or to leave for education or work is a difficult question. While there are advantages to both options, I believe that living separately is more beneficial.
