So, it was the first time 3 elements lined up. My girlfriend was at work this evening, I was wearing a diaper, and the need to poop was being felt at another hour than 8am. I was at the supermarket when the urge hit me, but I decided not to act there, in public. When I got back home, after putting the groceries away, I decided to just squat, and let loose. It was a firm, but not hard, load. So, with time to spare, I went to sit at my computer, do some stuff before cleaning up.
BTW, maybe a gross detail, but when cleaning up, I was feeling tiny prickly shards sticking on my skin. Found out they were popcorn shells. Guess that does not get digested, since I ate that yesterday.
