Who pees his pants in the back of the kindergarten classroom ?

Luis wets his pants in the back of the classroom. He could not communicate with his teacher, thus, he could not ask her to use the bathroom.

It got so bad, I didn't even tell anybody when I had to go the bathroom. I did it in my pants. Soon I stunk back there in the corner and the rest of the kids screamed out a chorus of "P.U.!" resulting in my being sent to the office or back home.
