It's kind of like printed-out email, but slower

I'm taking up Mary Robinette Kowal's challenge of a Month of Letters.  Basically, the idea is that you mail a letter (or postcard) every day there's mail service in February.

I wrote a letter last night that will go out in today's mail. It was kind of fun to put pen to paper and write — it's been a few years since I wrote a full page of something (other than notes) by hand.
