"Edam Hurst, you have positively the worst singing voice I've ever heard."
He smiled and told her to be quiet, kissing her to put more force behind the command. Then, hand in hand, Edam and Eeb walked through their glen.
The names of those congenital skeptics who insist that time-travel is impossible, even in theory, are Legion. Nor is their stand difficult to comprehend. They say that no man or woman has yet traveled backward to meet a younger him or herself face to face. They say this is immutable paradox. And by way of clincher they add a query as to why, if time-travel is to come, has it never happened? Why haven't we recorded instances of visitations from the future?
However, those in favor of time-travel have answers ready and waiting. These optimists (?) use the parallel universe theory to meet the first question. Such return, they claim, would immediately cause a forking of the Earthways, leaving our version of the world untrodden by time-traveling feet. As to the clincher, they counter-question with a How do we know we haven't had such visitors? Time-travel, when it comes, will come in a far-distant future. At such a distance the mere six thousand years of recorded human history is a mere fly-speck on the annals of Earth. So why should this tiny dot in the continuum have been favored?
