Loneliness is a ghost who lurks. It's not scary like a monster that can do violence. Rather, it is a Nothing that replaces Something. Anything it can replace, anything allowed to be released will be filled with this Nothing.
Loneliness can come without announcement and be present for long stretches of time undetected. Like an invisible leech, it can drain a person of the very thing that gives life. Loneliness is a parasite that kills slowly. It can be ignored by distraction into media and technology. It can be ignored by ritual, habit, and addiction.
I meet a lot of lonely people. You do too.
What can challenge loneliness? Meaning.
People must experience meaning in their lives. People cannot experience meaning in solitude. Friendship is the antidote to loneliness. Not aquaintances, not associates, not membership, not the number of people around - friendship.
Friendship is meaning.
