A courtesy flush to kill the world

At first it just seemed like coincidence, but now I'm fairly certain that all women in Japanese public bathrooms do this: courtesy flush--even if there's nothing to be courteous about. After all, it is a bathroom, albeit public, we have the same basic behaviors in there. We might be more vulnerable to a few noises of the gastrointestinally-challenged, but it's no cause for alarm. However, in Japan, even the sound of trickling pee is too much to handle. The moment a woman sits down, she flushes the toilet. Thereafter, she flushes it again many times, so that none of her stall mates have the slightest idea what's really going on in there. Is it really such a mystery? There's only a few things that someone would really spend the time doing in a public bathroom. So, why waste the eight gallons of water per flush simply to create the illusion that all you're doing behind closed bathroom doors is flushing a toilet? We know that's not all that's going on in there. Give it up girls, I wanna hear you pee for the sake of letting the environment be!
