Nostalgia

‎"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, and 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 are loved. " - don draper
