" Dad says that the world is always changing, every second of every day, and so is everything in it, which means that the you you are right now is different from the you you were when you started reading this sentence. Crazy, right? And your memories change, too. (For instance, I swear the teddy bear I had growing up was green, but according to my parents it was orange.) But when you take a photograph, things stay still. The way that they were, is the way that they are, is the way that they will always be. "
