Lucille completed the plans for her time machine.

"Hello, Lucille!" said an apparition that appeared out of nothing.

"Who are you?"

The tale has been stolen; if detected on Amazon, report the violation.

"A 'future person,' if you will. I've come to meet the inventor at the moment it was invented."

"Oh, so it does work?"

"Umm. I mean, yeah, sort of. As you can see, I can't use a corporeal body. I'm in a state of quantum flux."

"But time traveling does work? I can use my machine!"

"Time travel works! But it'll be about 300 years before any energy source becomes available. But it does work!"

Lucille sighed and frowned.
