Those who care will be there. No matter how far away, they will find a way to bridge the gulf that lies between. It is just a step across the expanse, for spirit knows no distance.
Enemies could not be farther apart. No matter how close they are physically, inside is a chasm that cannot be crossed. The wicked spend their lives in solitary confinement.
Loneliness comes from a lack of caring. Isolation sets in, and the person becomes a thing. They wander through the multitudes, alone in the crowd.
It is a cruel fate to be left to the mercy of one's thoughts. There is a desire to burn all bridges until one truly becomes an island. The point will come when no one can get in.
People are what they are, for better or worse. One can live among them or die alone. Never let what irritates you about a person ruin the enjoyment of your time with them.
The lonely must seek out those that care. Despite appearances, they still exist. Such will not be what is expected nor even what is hoped, but they just might be what you need.
