Review:
A few years after the fall of Voldemort, Harry and Severus find themselves inundated with thousands of tiny, tiny letters. Who from? Dumbledore, of course, who isn't going to let a little thing like death stop him from matchmaking. This leads to massive alcohol consumption on Severus's part, which leads to him inadvertently sending Harry a Very, Very Bad Letter, and that leads to...well, you'll just have to read to find out.

Going Postal is cute and fluffy and features some of the best letters I've ever seen. Hell, if more epistolary fic featured letters like this, I'd probably read more of it. Favorite bits: *every* *single* *letter* beginning with "By the time you read this note, I will most certainly be dead.", Harry getting a letter with "...don't imagine that Severus is the only one capable of acting like a stubborn arse, Harry", the 'suggestion' that Harry and Severus hold hands at a Quidditch game and take little children on a picnic, and, of course, you can't forget the Very, Very Bad Letter Severus sends to Harry. A delightful pop-tart to brighten your day.
