I'm beginning to suspect my neighbor in the apartment across from me is a hikki. I met him only once, when he peeked out of the door when I was moving in. Since then I have never seen him leave or come back from his room, and there are almost always sounds coming from his room even if it's a time of day where most people would be out at work.

The final clue is that he gets a ton of packages. Almost every single day there's another package in front of his door or a notification slip for one. Today there was a new LCD screen waiting for him, I hope he enjoys it.
