Twilight Hue
Twilight, not bright nor dark, good nor bad.
Apologizing gives one's opponent a swelled head.As for why some people don't apologize, they're probably subscribing to the wisdom expressed by the Duke himself:
I never really subscribed to this notion myself, although in a predatory culture where people are taught to keep a stiff upper lip, to always show the tough face, never let them see you sweat, and never show weakness, it's not too surprising.
Otherwise it's a good thing. Particularly if you accidentally drop a hammer on one's big toe.
