Writing Prompt / Story Starter 8

Thomas couldn't believe nobody else had noticed the cloud. They must have seen it, the cloud shaped like an infinity symbol, that sleeping figure eight. It had been there for, what, four hours now? Other clouds had come and gone, shepherded on by the wind, but this one had remained.

They must have seen it. Thomas could only surmise that everyone else had opted to ignore the cloud, had blocked it out somehow. And who could blame them? It was simultaneously meaningless and mind-shaking. An armada of alien spacecraft would have been similarly mind-shaking but it would also have been meaningful; it would have been a frightening sight but, ultimately, one which could be processed and dealt with. But an infinity symbol cloud which refused to do the natural thing and obey the elements? That was all kinds of weird.

Then, Thomas noticed the woman, petite with short black hair and a pronounced underbite. She was staring at the cloud and smiling.
