If we all took media messages at their absolute face value, we'd all be sleeping with our best friends. And that does happen, sometimes.* But herein lies the trap: We've also been trained to think this will always work out over the long term, which dooms us to disappointment. Because when push comes to shove, we really don't want to have sex with our friends... unless they're sexy. And sometimes we do want to have sex with our blackhearted, soul-sucking enemies... assuming they're sexy.
