The world is a scary place.
Unlike most scary places, & most scary things, & most scary people, you can’t run from it. That only makes it scarier, knowing that you can hide, & you can run, but no matter how hard you try you can’t run away from the world, & hide forever, without returning even for a visit. It’s not possible. You’d get sick of the new place, or get lost & end up back here, or maybe simply run out of oxygen.
