In the past couple of weeks, I've rediscovered a website called Postcrossing, which facilitates sending postcards across the globe. People who register on the site initially receive up to five addresses of other people registered on Postcrossing. You mail out your postcard(s), and when the recipients receive and register their newly received postcards, you are able to get additional addresses to mail more postcards. Whenever you request a new address to send a postcard to, you get a unique ID number to write on the card. The person on the other end types in that ID number to indicate receipt.
Although I registered on Postcrossing about three years ago and sent/received a few postcards then, I got busy with other things and forgot about it. I just recently signed back in and decided to send out five more postcard and see that happened. Since then, four of my postcards have been received overseas, and I received two postcards yesterday, one from England and the other from Germany. It was fun to get some non-bill/junk mail in the mailbox, since I keep up with so many people by email, Facebook, and Twitter now.
This newly refound hobby will probably fade away again in time, but for now, in these drearier days of fall (did I mention it's been raining all week thanks to Tropical Storm Ida?!), it's fun looking forward to colorful mail via postcards in my real live mailbox (not the virtual one).
