Your letters

Every letter you’ve sealed lives right here on your device, counting down. When one’s day finally comes, it lights up.

Letters from the past

People have always written to the future. On paper that had to survive attics, wars, and being forgotten. Here are three that made it.

• 1972

  to her granddaughter, on her someday-wedding day

  Margaret, 61, a schoolteacher

• New Year's Eve, 1999

  to his son, at 34

  David, 34, holding a video camera

• 1936

  to whoever finds this

  A stranger, sealing a time capsule
