Passive-aggressive notes. I love to hate on them, and they often make me laugh. There was recently a post that had to do with brothels and such, which I wanted to link to. Taste the bittersweetness that are passive-aggressive notes!
This photo is apparently from the good old Soho area of London, so I guess I need to poke around now and see if I can find it.
The blog itself makes me laugh. I promise TB that the note on your door is a mild version. Check it out. You'll laugh so hard you cry.
