There's something about a postcard.
The stamp. The cancellation mark. The scuffed corners and little indignities picked up somewhere between there and here. And the fact that someone took the time to write it, address it, stamp it and send it when just a text would have sufficed.
By the time it arrives, it's more than a message. It's a small artifact of a human connection that mattered enough to go the long way 'round.
