The truth.

[Audio recording started.]
Hello there. I don't know who will find this, but I hope that you do. And I hope that he looks away and gives you an opportunity to see this. There is something that you should know about Garfcord. 
It is only you and him. 
I know this seems strange. What about all of the people you have met? All the connections with the people you spent all that time making? Simple. They were all false. This may seem like a prank, but I assure you, this is very real. I am one of his earlier victims. And by Garf, I hope that my fate does not befall you. He sees this like a game. How long can the veil be draped over your eyes before you notice things? Similar typing styles (comnedic mispeling), familiar symbols (:3), seemingly an echo chamber for the same 2 damn games (Ultrakill and ROCK AND STONE). These little things slowly continue to build up. If you think that this is some inside joke, you start to see it as normal. You expect to open chat one day and see the usual Goobers going about their daily business. You may try and talk to them, but only he shall respond. He runs everything.
But why would he do this? Any of this?
To keep you busy.
While you were listening to this, he has stolen your copper wiring.
