Your Sex Life Ain't My Business, or "Look Mommy, I made a potty!"

Have you ever been whacked over the head with somebody else's private life? You know, the part where they show up at a party with n>1 people on their arm and make a big show of kissing each of them in a fashion that really calls for a bed and a closed door? Or when they make a big show of their tongue piercing code, especially when it indicates that they're lesbian or gay? Or when some guy you don't know very well goes into *way* too much detail about his prostate and the stimulation thereof, or some woman decides that right here and now is a great time to discuss her menstrual flow?

It's not that doing any of those things is wrong, or any such bunk. It's just that talking about them in front of strangers in a setting where that's not the mutually-agreed-upon theme of the event is in extremely poor taste. Most of us get the "appropriateness" thing down by the time we get out of diapers. The rest are really behind schedule.
