Eureka! Discovery of one of the best blogs ever: passive-aggressive notes from roommates, neighbors, coworkers and strangers. And, I'd add employee-of-the-month sociopaths.
I had forgotten about the passive-aggressive note I received on my windshield when I unknowingly parked in the special parking spot of the employee of the month at a public school district parking lot but spending a little time at this blog brought the memory back. If I remember correctly, it contained a threat. It was definitely a WTF moment.
