As a little bit of the icing splattered about, some of it landed on the note, causing it to soak up some of the moisture, causing some of the previously hidden ink on the flip side of it to react.
"P.P.S: If you're reading this, then someone attacked the note. I can only guess why. Maybe it's the irony that I'm not here and left a note after leaving a big stink over doing exactly that? Well, nobody this note is for should have any problem reading it, and if you're not willing to accept an apology, then choosing not to be present was a good call on my part. If there's anymore to it than that, then address your complaints to me directly. I don't want there to be any bad blood between our clans.
