For a thing to be special, it needs to be rare. Special things are uncommon, a field of grass in the middle of the prairie is just scenery. A drop in the ocean, as they say.
The reason they make so many movies about "true love" and "soul mates" is because it isn't something that happens everyday; it is a fantasy movie about some fantasy shit, so to speak.
The measure we use to determine happiness is based on experience. If you've never been happy, a small kindness can mean the world. If all you've ever known is blissful ignorance then a minor inconvenience is a gross misfortune. This is why children over-react to everything, they simply don't know any better.
Likewise, if you've never known security then you have no idea of what safety means. If you've always been beset upon by those mean you harm, you wouldn't know a good thing if it hit you in the face (because that's normally what the bad things do).
And if you're always angry, you'll know no peace.
Experience is such a trivial thing and yet it is the lens through which we see the world.
