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.
