It's more that if you know what it takes to cast those things, you know where the weak side will be if some tries using them against you. I realised this term that you learn a lot of that sort of thing by trying it.

And maybe it won't matter. I mean, maybe I won't have done well enough. But if I do, then I'll have to figure out what to tell Mum. It would be easier if I could still just talk to Dad about this sort of thing. But, yeah.
