Nostalgia. It’s delicate, but potent… Teddy told me that in Greek, nostalgia literally means the pain from an old wound. It’s a twinge in your heart, far more powerful than memory alone. This device… isn’t a spaceship, it’s a time machine. It goes backwards, forwards. It takes us to a place where we ache to go again. It’s not called the Wheel. It’s called the Carousel. It lets us travel the way a child travels. Around and around and back home again, to a place where we know we are loved.

-Don Draper, Mad Men
