On my hard drive, I have a place I archive old mail. I have a number of folders organized by type of mail. One folder is titled, "Queries." By the whim of alphanumeric order, the folder, titled "Reviews" falls right below it.
As I was sorting mail, I accidentally clicked on the wrong folder, and opened an old letter from Queries. It began, "Thank you for sending me your mss, but I'm afraid I just didn't love it."
Oops. It was a letter from one of the many, many agents I had queried once upon a time.
I clicked the right folder, the right letter. From a reviewer. "Thank you for sending me your book. I LOVED it!"
Same book. A year later.
Life is sweet.
