Doors are such a common, everyday sight that we pass them and pass through them without giving thought to the role they play in our lives, our mythology, our fiction.
They act as barriers and gateways.
The doors to our home keep us safe from the things that go bump in the night. They keep us safe from the world. Sometimes, they keep the world safe from us.
They are entrances. And exits.
They are in-between places. Stand in the middle of a doorway and you’re neither in the place you’ve just left nor in the place you’re going.
