Decency here is not in contrast to the indecency of, say, wearing two different-colored socks or not having your zipper done up. We are talking about decency as something more profound to be realized and understood. The first part of decency is what is called modesty, which here is the absence of arrogance. The second part of decency is being so kind and wise, but without laying your trip on others.
Decency means never being tired or made haggard by others. There’s always some enjoyment in dealing with the world, whether you are dealing with people, with other sentient beings, or even with inanimate objects. You could be dealing with your garden; it could be your horse; it could be your dog, your cat, or your stove. No matter what you are doing, the sense of decency is being absolutely on the spot, without falling to the level of uncaring and crudeness
