Interview #1
Greetings, 8123-C. We are here to ask you questions about your surroundings and what it's like where you are, if that makes sense.
Ok, first of all, why are you calling me 8123-C, why do you need questions, and why do you need to know what it's like where I live?
Because what else should we call you?
Because we need t…
What does it matter to you anyway?
Do you know who you're talking to?
I'm the most well known being on the planet!
I don't know anything about you.
I'm assuming that's because we're on different planets.
Seems like it.
Anyway, since we got that out of the way, could you please do this interview?
Alright fine, but please hurry up.
Thanks.
Ok, first off, just describe your surroundings now, please.
Basement in a giant castle on the side of a mountain. I live in the castle, not just the basement.
Well, that's quite an interesting setting.
You live in a monarchy or somethin'?
I mean you could compare it with a monarchy.
But, no joke, that's all you're getting. I don't know who you are, and I don't trust you with this info.
K, then. You good with doing more of this at some point?
Um, if you don't wanna know my literal coordinates within this universe, then sure.
Alright. Bye.
Bye.
