I have to pee really badly, and someone else is waiting to use the shared bathroom too, so I have to be quick about it. I pee, fart a couple times, and blow my nose. When I'm almost done and getting ready to wipe, you'll hear a REALLY loud, funny sounding fart that sounds like a machine rifle that surprised me too! I sit back on the toilet and laugh, hoping that the lady waiting outside to use the bathroom didn't overhear. I finish up and wipe and then flush the toilet.
