on the down low

Somehow intoxication creates a level of candor that you don't often find in "real" life when people are ever vigilant about keeping up appearances. This is why I like to get drunk with guys, I learn something new each and every time. Especially when it comes to the games they play with the ladies. This weekend somebody said something about wanting discretion. They said that they were all about discretion, not wanting anybody to know their business. But aren't you really only discreet about the things that you're ashamed of? You don't boast about your drug problems, your porno addiction, your fifteen foot by seven foot altar dedicated to Alan Cummings. So is discretion basically cowardice disguised as privacy? Or am I missing something here?
