I have massive respect for you for not doing it. I...am not so good at impulse-control. :p And, take it from someone who has hit people in anger before - It might feel good at first...but you'd regret it later anyway, so in the long run, it's not really worth it.

I'd teach Miyuki too....but she's got attitude enough that I bet she'd be a real scrapper, with or without formal teaching. She doesn't take crap from people, and that's just how she is, so I don't think she needs it.
