There's always running. That's the advice I always give to people with smaller frames. If you're not built for violence, and its not in your personality, then you should run. You should get really, really good at running. And dodging. Dodging helps.

Because think about it.

How are you gonna feel if you hurt someone?

You're gonna feel pretty shitty, right? Even if they deserve it, you're gonna feel bad about hurting them, so you should just learn to keep yourself safe enough that other people don't have to worry about you while they're handlin' bigger issues, right? And its real easy to learn to run.
