I'm surprised! I thought that you people of the future would play more tricks than we do.
Some people would say it is rather arrogant to abolish a thousand-year-old tradition because you think you know better. Perhaps the current headmaster sees that, even if he doesn't like the rivalry.
I'll be going back to Hogwarts, though. Cassiopeia is teaching me here and she at least tries to make things interesting. I doubt she'd approve of 'my own pace,' I have to say.
