When a not-so-brilliant man and his similarly equipped wife find out that one of them is
destined to invent time travel, they end up continuously fighting, not the least cause of
which is their future selves popping in all the time, intent on informing them that they
should do
this and not
that.
— Michael Main
Being the future inventors of time travel wasn’t all bad, of course. It was great to
know that we’d never lose anything, never go to a movie that turned out to be a
stinker, never buy a book we wouldn’t want to finish, never go out to a restaurant
where the service was lousy, and never get stuck in a traffic jam, because we’d always
be warned away, beforehand. It was terrific to have some future version of myself pop in
just as I was about to irritate my wife with some inconsiderate comment and tell me,
“It would be a really bad idea to say that.”
