I indulged my paranoia: I took a picture of the little girl across the street. Click. Snap. And there it was. Photographic proof that she existed.
Except she didn't show up. The image was of an empty sidewalk. She was there, but she didn't show up. I looked again and she was still there. I snapped a dozen pictures of her. Each one the same: nothing.
Was she a figment of my imagination?
Should I ask them? Should I ask my neighbors if they actually have a daughter? Can I do that?
What if the answer is no?
