When I was younger, maybe 12 or 13 years old, I would daydream about sending a letter to my future self requesting he travel back in time to show me the future. I imagined that I would ask to be collected on the exact date and at the exact time I deposited the letter into the letterbox, so that the time portal would materialise next to as the letter left my fingers.
Unlike most contemporary forms of communication, there is no direct reaction to sending a letter, no dial tone or “sent” confirmation. Instead, there is a complex process, an entirely hidden industry, that connects the letterbox to the rest of the world. The mystery of this process establishes the likelihood of magic.
