"I don't duel, boy. I kill as a soldier kills, which is as a butcher kills, as quickly, efficiently, and with as least risk to myself as I can arrange. If I decide you die, you will die when I choose, where I choose, by what means I choose, and you will never see the blow coming. (...) I don't duel. But if you seek to die like a bludgeoned steer, cross me again."
Lois McMaster Bujold
