Dementors Everywhere

In the Harry Potter books (and movies) there are creatures called Dementors - creatures that feed on misery and live by sucking the happiness out of everyone (see clip above). It's a perfect representation of those people you meet in the everyday who just seem hell-bent to bring you off your high and into their low. Why? Because misery loves company?

Unlike the dementors in Harry Potter, though, chocolate alone won't make the chills go away after an encounter with these emotional vampires.. it requires a little more than that. Literally, you need to work on building up your psychic self-defense. A tight bubble of positive energy around yourself that can't be touched, drained or perforated by their attempts to bog you down.

I certainly have my fair share of personal dementors. Any other good tips on dealing with these creatures in your office or in your circle of friends?
