Cloud Over My Beautiful Beach

In one of my worlds, there is a simple & common english word that is not used.
You start out in that world with all your standard vocabs. After a few years, you drop this word like a hot rock.
Sorry.
Sorry is a sign of weakness. It is an acceptance of all guilt. Any guilt.
In that dog-eat-dog world, the weak are the hunted.
The dogs don't ever stop sniffing for blood once you utter that word.
The prize is all that matters. The sooner you get to it, the quicker you can get to the next prize. And the next. And the next.
