Did you ever, after a particularly noble dump, turn around and look in the bowl? There's no need to answer aloud or anything... even though I would hear you if you did. Wooooo... But, no, there's no need to answer. I already know what you'd say.
Did you ever, having seen the massive shit you've deposited, cogitate over the fact that you've been carrying that dirty bomb around in your body for the past few hours... Unpleasantries, I know.
Did you ever, having cognitively made it this far, look at another person and realise that they're little more than a frail bag of meat and fat, literally filled with shit. I sometimes do. Though I wish I didn't.
