Dear Lamp-post: Once upon a time, Professor Dumbledore walked down the streets and made every single lamp post light up at his will. And then once day when you wake up, you realize that you are left all alone in the world. Never mind that Dumbledore has passed away and they changed the actor. Never mind that the new Dumbledore will be dead by the half-blood prince anyway. Never mind that you may have never even seen Dumbledore anyway. You know what? You have a friend and there he is leaning on your shoulders.
