Prompt: Thursday Scene Elements 1

So, on Thursdays I will give you elements to include in a scene.

An opening door

Light

That's it. I know it's only two elements, but think of the possibilities. Where does the door open? Is it opening to walk into an office building for work? A bedroom? It it a screen door that opens out into a garden? What if it's just a metaphorical door opening? Or maybe a door cut into the fabric of time...

Is the light natural or artificial? Does the opening door cast light on the scene? Is light filtering in through a window?
