Learned a few years ago that some people wipe standing up. Mind blown. Found out because a guest left poopy toilet paper shrapnel on the ground in front of the toilet. Roommate and I concluded the guest wiped standing up. Couldn't think of any other reason for the poopy toilet paper remnants. Because of this experience, wiping standing up is just as much of a sin as having the toilet paper roll on the wrong way (flap on bottom is wrong).
