The masterminds at Westword bring us a hand-dandy flow-chart on the art of subterfuge. Or, as they call it, a "Forensic Psychology infographic." Never be played for a sucker again.
I hate it when people use "I'm just being honest," as an excuse to be rude and or offensive. I'm okay with white lies, they have their place, and half truths at the office of the "no, nothing is wrong," variety are unfortunately often times necessity to avoid getting black balled.
I do both of these things a lot, but i feel like a very honest person. I never betray anyone. I don't make promises I don't intend to keep, etc.
