Don’t do that. Don’t skip stages in your life. You’re 19, kiss a few boys and wear your heart on your sleeve. There will come a time when you’re 39 and stuck in a suit, wondering why the hell you were so eager to grow up in the first place.
It happens to everyone as they grow up. You find out who you are and what you want, and then you realize that people you’ve known forever don’t see things the way you do. So you keep the wonderful memories, but find yourself moving on.
