I used to think most everything was pretty black and white, right and wrong, but what I realize as the years pass is that the world is mostly in the gray.
A lot of things are dark gray, and pure white seems to be a rarity. There is a lot of things that seem white but are black on the other side, or tinged with gray in some contexts. There is a lot of things that seem absolutely black but are actually white when some light is thrown on why it happened.
I guess we're trying to figure out how to differentiate. Some people are also chasing after pure white, but I think the wise thing is to accept light gray and be grateful it's not darker.
