When putting up a building or sailing in the deep, you learned to watch over one another; an enforced togetherness emerged, a brotherhood of sorts. A tacit understanding ruled across the ranks.

So you buried the dislikes and the fights, unless a mutiny erupted, in which case the world would be turned upside down.
