So you use 3-4X as much water so people don't hear you pooping?  Don't you think that's a little vain and irresponsible in terms of insecurity and consumption?  I mean who cares???  It's poop!  I like to pretend I'm Chris Berman when I poop- I'm all like "WHOOP!"  or "BACK, BACK, BACK, BACK, AND IT'S OUUUUUTTA HEEEEEEEEEEEERE!" in public bathrooms.  Especially if I'm shitting loudly.  Sometimes I will laugh if it makes a funny noise.  I guess I just have no shame.  You should try it, it's fun not to give a fuck.
