Haha!
True story. When I was in high school, I was in wood shop way away from the rest of the buildings on campus, so there was no hope of finding another bathroom. I got sick to my stomach and had to go RIGHT THEN. On my way in, I realized there was no t.p. anywhere, so I had to improvise fast. Just so happened I saw a paper bag from Burger King in the trash, right inside the door. That's what I ended up having to use. Just FYI, paper cuts suck, but they can suck even worse.
After that, I decided I'd rather go in the woods if need be.
An extreme situation, I think you have to live and be in that moment for sure nerves invade completely, thanks for your response
