I draw the line at violence.
Slap my truck as you go by, flip me the bird, yell at me until you're blue in the face.
But don't play "Violence" with me. You can't touch me, you can't break my windows, you can't take my things, like wallet, keys etc.
I draw the line at violence, because if you get between me and the exit and threaten my safety, it's on.
