Attic Philosophy

John and David had been laying in the attic for three hours, staring at the ceiling. They each had considered starting a conversation or something after the first half hour, but after so much silence they both decided it would have been too awkward. They were right.
"Do you ever think..." said John. David jolted in his spot.
"What?" said David, catching his breath.
"Do you ever think that we're... like... being watched all the time?"
"How so?"
"You know, like, what if someone is aware of us wherever we go and knows what we do?"
"Don't give me that 1984 shit, man. We're not in middle school anymore."
"Fine, fine."
Several minutes passed. David thought about excusing himself to the bathroom and not returning. Eventually, he didn't.
"You know," said John.
"Whaaat," droned David, rolling his eyes.
"I'm really not talking about 1984 shit."
"Sure you're not."
"No, really! I'm not talking about the people around us watching us at all! It's more of an... outside source."
"Oh, so instead of 1984 shit it's Matrix shit. Brilliant."
"Oh, goddammit David."
David sighed.
"Can I finish?"
David grunted.
"Fine. Like, have you ever seen a sci-fi TV show?"
"Of course."
"Ever seen one with time travel?"
"I guess, yeah."
"You know how they're always watching the past on a video screen? They're, like, watching the people do what they're doing, even if the moment wasn't filmed."
John smiled expectingly.
"Oh."
John bit his lip.
"You realize those are only TV shows?"
"Yeah, but if could happen. They've got until the end of human existence to invent the thing and still watch me do whatever!"
"So?"
"So!? So what if they're watching me all the time?"
"Why would they bother doing that?"
"I dunno, maybe I grow up to be a king somewhere or something."
"A king, John?"
"I dunno, it's a rhetorical."
"Hypothetical."
"Oh, hypothetical."
"Yeah"
"Are you sure it's hypothetical? That doesn't sound right."
"I dunno."
"Anyway."
"Anyway."
"Yeah."
"So... so what, John? Who cares if some hypothetical..."
"Hypothetical?"
"Hypothetical future person is watching?"
"Well, it's creepy is all."
"I guess," said David, "but don't you think you'd have scared them off by now?"
"What?"
"Well, if I was a futuristic voyeur and my target started talking about me, I'd be totally weirded out and leave. Your future people just totally ditched you, dude."
"Oh," John looked disappointed.
"You definitely lost your audience, man."
"Well," said John, "um..."
David went back to staring at the ceiling.
John smiled.
"What?" asked David.
"I can finally start masturbating!"
David looked at John with one cocked eyebrow. David got up and walked towards the ladder back down to the house as John stuck his hand down his pants.
