When I think of analog activities, I immediately think "handwriting." And that connects the dots to letters and postcards. Can't think of a better time than now to be staying in touch or saying hello to friends and family the old-fashioned way: write something and send via postal mail.
Besides, America's postal system is threatened and needs more support! So that makes this idea a win-win.
Notegeist has an easy, fun way to get your started: Quotable Notable cards from Unemployed Philosophers Guild. Check them out, grab a few, and get started connecting the analog way through the mail. With nearly 20 famous people featured, there's bound to be one that resonates with that special friend.
