Pietro had to bite his lip to the point of biting through it to keep from laughing at the VERY obvious hole in Boor's trousers. Serves him right for being a foul human being treating innocent students like dogs. Part of him felt very traumatized at seeing this old man's rear end. Then it hit him: THERE WERE GIRLS IN THIS CLASS THAT DID NOT NEED TO SEE THAT. Hell the GUYS didn't even need to see that. EVER. While Pietro stood up and stretched his arms above his head, he wondered exactly WHAT he had gotten himself into. Because this man was clearly insane in ways that not even a child with Pietro's background could imagine.
