Conversation with a Time Traveler

"So... you're from the future?"

"I'm from a future. Obviously, I can't be from your future, because by coming here I've altered your timeline and thus my own. Paradoxes and multiple universes and so on. I think string theory has something to do with it."

"And... that's why you have that thing on your head?"

"Oh, this? No, we evolved a symbiotic relationship about a thousand years ago in my universe."

"With squid?"

"Have you ever felt rain through a squid's senses? Your kind don't even have words for what we can perceive together. And now you never will."

"...Pity."
