Dexter: what's in that wall panel?
Me: a time vortex spanning the universe.
Dexter: I don't believe you. It's too thin.
Me: that's the glory of the time vortex; it fits in small spaces.
Dexter: time vortexes don't exist.
Me: how do you know? I mean really, How Do You Know?
Dexter: I've never seen one.
Me: you've never seen a zebra. Maybe they don't exist either.
Dexter: Zebras exist. they are in books.
Me: so are time vortexes.
Dexter: yeah, but that's SciFiction Mommy.
Me: still, how do you know zebras exist and not time vortexes?
Dexter: cause people come back from trips saying they saw zebras. no one brags about seeing a time vortex.
Me: shit. you win.
