Humans are also social creatures. Even the introverts among them crave interaction—not necessarily with other humans, but rather with the residue and output of those other humans: books and music and art, to be contemplated and perhaps even created. No human is an island. They are rarely even peninsulas. There is a reason why one of the greatest punishments of humanity is to be placed in a solitary confinement, even for a short time. Being alone is another thing to remind them of death, a condition in which there is no one else and will be no one else again, ever.
