There's something sacred (and romantic, in the broadest sense) about communicating in the way generations before us once did. We've all heard the stories: It's how your parents communicated with Santa Claus, it's how grandma and grandpa kept their love alive during wartime, it's how immigrant families and friends separated by their respective moves shared written snapshots of their new lives. Computers and smartphones may prove more efficient, but they can never take the place of this kind of sentimental history.
