AT THE BEGINNING:

There comes a point in your life, when you’re officially an adult. Suddenly, you’re old enough to vote, drink and engage in other adult activities. Suddenly, people expect you to be responsible, serious, a grown-up. We get taller, we get older. But do we ever really grow up?

AND IN THE END

In some ways we grow up; we have families… we get married, divorced… but for the most part we still have the same problems that we did when we were fifteen. No matter how much we grow taller, grow older, we are still forever stumbling… forever wondering, forever… young.
