I went to look out the window in the empty office next to my cube, and in the parking lot below I could make out two women. They were talking to each other, and walking, in unison, backwards. They did this for at least fifty feet.

They continued walking and went behind and under a tree, and out of my field of view. When they re-emerged, they were walking forward again, still talking.

I’d write a story about that, if I could think of any justification for it at all.
