Separate Ghost - flash fiction

I spent nights watching walls. Car headlights slithering past, in a series like cards falling.

The traffic continued. On full moons the moonlight would shine cylindrically on my face.

I finally saw him one night walk into the living room lit with hovering headlights. I saw his upright shadow for a moment. He disappeared after a couple of steps.

I left the beacon of the living room out of fear. I took some breath outdoors. In front of the house gate the upright shadow arrived again. A few paces and it left. Was this a pattern?
