Sounds a lot like a guy I knew. He would write letters to himself and pretend that government officials had sent them him. He would then reply and give it back to himself. Really shocking. He also killed his hamster by drowning it in alcohol, thought it was bugged or something. One day he came to my house and shit on my floor. Liquid shit, splattered all over the floor, with corn, peicss of carrot, and little nuts sprinkled all in the soupy brown mess. It stunk like hell. Let the dog clean it up by licking it up. Can’t blame him, it didn’t taste that bad. Turned out later he had schizophrenia, and hung himself in the hospital. He also had worms, so that means I got worms too. Bad day that was.
