When I was in elemenrty school I was in a computer class when I raised my hand and asked the teacher if I could go to the toilet. She said I could go after she was done explaining. I couldn't wait for her to finish explaining the new work, so I sat in my chair and silently pissed in my pants. After class had finished I stood up and slowly tucked my chair in, which was full of piss. No one suspected a thing. I regret nothing. Unlucky to the the kid who had to sit at that computer in the next class.
