I love a good passive-aggressive note, if it's not aimed in my direction. I don't think I've ever written one, but I did get one pretty recently. It was for parking too close to someone's driveway (parking in Austin is just atrocious), but I think that's the only one. I've never left a passive-aggressive note for someone who has upset me. I've wanted to, but never have.
You guys liked the previous post about passive-aggressive roommates, so here are a few general passive-aggressive notes.
