Dear Hannah,

You’re going to adopt a dog in three weeks, and that will change your life and improve your mental wellness and bring you so much joy, and I’m so happy for you.

But we had a dog this week who needed to be euthanized because we couldn’t find a home for her. And we know you two would be absolutely perfect for each other. Your life would be even better with her in it.

Maybe consider coming down two weeks earlier?

PO Box 159 at the Brooksdale Post Office is a bit unusual. Every week, it receives letters from many different people from many different times in the future. Many times, the letters are well-wishes and advice from the loved ones of people of our time. Other times, there are dire warnings.

No one seems to know how or why these letters started coming to PO Box 159. They simply appear. The future these letters describe seems to be in constant flux; one day the year 2098 sounds like a dystopian hellscape, the next day a letter will appear describing a garden of Eden.

Emma Reilly, the owner of PO Box 159, shares the letters she receives through this blog (mostly) every Tuesday.
