You know that time when you were riding on the bus and listening to music through earphones and that person across the aisle from you suddenly gave you a really sharp look? It might be because the flatus you just released did so with a little more fanfare than you could hear yourself. Remember, this is Spokane. Not everyone on the bus has their ears plugged into a music player.
As to whether I'm speaking from experience, don't ask. Besides, I probably wouldn't hear you anyway since I usually have the volume up pretty loud.
Why are you looking at me like that?
