My latest guilty pleasure:
I've only recently discovered this site, Passive Aggressive Notes, (www.passiveaggressivenotes.com) and have since spent far too long perusing the notes and laughing myself into a tizzy. The site bills itself as "painfully polite and hilariously hostile writings from shared spaces the world over." It may help you realize just how petty some of our/your issues may really be. Seriously, it's amazing what people will write (rather than say) to other people. And, I know that my college roommates and I could have been the stars of a site like this back in the day!
(And, if you like those Passive-Aggressive little letters, you may like Found).
