A mysterious meeting

I was doing my laundry today - I tend to do it pretty late, since it's cooler at night. So I was waiting at one of those tables outsides Starbucks (which was closed) while my clothing went through the dryer in the 24-hour laundromat across the parking lot. I was reading The Dream of Perpetual Motion by Dexter Palmer.

And then a guy sits down across from me. All the other tables are empty, but he sits down at my table. I looked up from my book. He was pretty old - at least in his sixties, gray hair, wearing a heavy overcoat, and a large-brimmed hat. He looked at me and said, "There are four kinds of people in this world: cretins, fools, morons, and lunatics. Which one are you?"

"Excuse me?" I said.

"I'm sorry." He spoke with a weird European accent. I think it was Italian. "I didn't mean to insult you. My name is Isaac. Yours is" and then he said my real name.

"How did you know that?" I asked.

"You don't know what you have made," he said. "You have created something which is far bigger than you. Now that you have created it, it has always been and always will be. Perhaps it was just waiting for something to create it before it could exist."

"What are you talking about?" I stood up.

"Even if you understood, it would not matter," Isaac said. "It isn't enough to have understood, if others refuse and continue to interrogate. You cannot stop it. You can only hope you do not get swept up in it." Isaac stood up then and narrowed his eyes at me. "I was like you once. I created something I could not control. I made it with my friends, like you. We made it up and it all came true anyway. That's the funny part." He smiled and turned to walk away.

I called out after him. "Who are you?"

He didn't look back, just muttered some random sounds - it sounded like "Ma gav tee la na ta." Then he turned the corner and left.

If this sounds like some sort of ARG thing, I know. I wouldn't believe it happened if I read it, but it did happen. I mean, I've had people say weird things to me, random things, but never like this. Fuck.
