See, my housemate is only home a couple of times a week. With my crazy hectic social life and locked-in-room-kinda-creepy blogging commitments, we only cross paths once every week or two.
So I think that if he does come home and I'm taking a shit, then the proportion of time that I'm shitting compared to the time that he sees me will increase.
I don't want it to get to the point that he thinks I have some sort of weird problem with my bowels that means I shit constantly. That'd be awful.
