I got my very first official fan mail today! Bounce!
Dear Eugie,
I missed the announcement of your story’s publication, but recognized your name in the current issue of The Leading Edge, and read your story first. With much pleasure. Keep them coming, and help maintain print SF/F.
The sender is someone from Critters who critiqued my last submission, but not one of my regulars. Someone who isn’t a close friend or family member read something I had published! 
I wish I had something more articulate to say, but…Go, you!
Wow, now that’s a chipper smiley face. 😉
