It happens to everyone as they grow up. You find out who you are and what you want and then you realise 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 - Nicholas Sparks
The Mad Hatter: Have I gone mad? Alice: I'm afraid so. Your'e entirely bonkers. But I'll tell you a secret. All the best people are. From the Mad Hatter's Tea Party in Alice in Wonderland by Lewis Carroll.
