Of course this was an accident. I was coming in with the mail, and this little envelope was on top. My hands were full, it slipped out of my grasp, and I was standing right by the water dish. Argh. I snatched it up and immediately opened it, and fortunately because of the thick paper, the wet was only on the envelope, and the letter inside was fine. You can sure tell which of the inks had a mix of waterproof elements, though! I smudged out the sender's name and address, but it was quite legible.
