A teacher that doesn’t take himself too seriously always will be a big hit with teenagers, although he’s not afraid to impose his authority if he has to. I’ve only ever heard him properly shout once (although thankfully it wasn’t it me), but it isn’t an experience that I would like to repeat. When he lost it, the room suddenly became more silent than I’d ever known it to be before. We all sat slightly paralyzed, not even anting to breathe too loudly, because hearing such a jovial and jolly little man lose his temper was a huge shock. It certainly had the right kind of impact though, because he’s never needed to shout since.
