The Square Root of Infinity

...concluding this little story...

The little bubble-headed alien told me what his name was but I couldn't pronounce it. He told me that was because I had a tongue which was, in his estimations, the biggest barrier to speaking the language of outer space, in addition to speaking the truth. I let his snide remark slide as we began our descent.

"Where is this place?" he asked in utter amazement as we both stared out the front porthole of his little starship. "This isn't the same Earth that we used to visit and monkey around with ."

"Well," I said, not surprised by the sudden time shift and unpredictable turn of events, including this bubble-head's spontaneous confession, "it used to be."

And then we exited the roving wormhole and landed.
