I'm a little worried about... the sounds that accompany the act of defecation, and there's a certain amount of anxiety that comes with having to urinate simultaneously ("Oh," I imagine the other guy saying, "you sit down to pee?"), but, as the saying goes, when you've gotta go... so I go.
My fears fade away, though, as I hear, coming from somewhere (where? the women's bathroom next door, the vents, where?) music, faint, but unmistakably "After the Gold Rush" by Neil Young.
There have been no sounds from the other stall, however, and maybe the music is distracting him from his business, because I hear him, whispering, "Jesus, shut the fuck up."
