This afternoon, I was pacing in public. I stepped perfectly in the tiles, perfectly keeping pace. Out of the corner of my eye, a little boy, walking just behind me in my peripherals. He had blue sneakers on. I assumed it was my little friend, coming to play. But I could've sworn his sneakers were red. And how is he being so quiet? I finally finished pacing, and whirled around to scare him, make him laugh his adorable little laugh. But there was no one there. No one at all.
