I just wrote a letter in pen and ink (well, ballpoint actually). It was a real letter that I put in an envelope and carried to the post box.
I have a friend in New Zealand who is not on email, and I wanted her to know we are coming her way early in 2012. As a very happy retiree she will also be interested to know how it's going for me. I was able to tell her that, among other things, I hope to be writing more real letters to friends.
Better add that to my growing "to-do-in-retirement" list.
