There's nothing here!

She is not where you were looking. She is not an address you can walk to. She is, perhaps, in a space with a door, by which we mean she is probably busy.

An empty space is empty.
Two empty spaces is a collection.
A collection is a room.
A room is, perhaps, a life.
A life is not so empty.

She has been reported writing things down. Reported: nowhere near at all — which remains the longest-running and most reliable sighting. If you have seen her, you are wrong. If you have not, you are correct.
