Everyone you love will eventually go away.
Some will leave you.
Some will be left by you.
Some will disappear into the great mass of humanity as you both turn your back for what feels like just a moment, never managing to reconnect again.
Some will be lost that strange darkness that overtakes people when they change — afterward, even though you may see what seems to be them every day, you’ll know that you’ve lost them forever.
Many of those that remain will die before you.
And the rest will leave your life when you die before them.
You will be buried alone.
