Loneliness is one of those things that makes you do strange things. I know that I've done some weird things with pillows just because I was lonely. For that reason, I completely understand where this guy is coming from. Sometimes you want a girl so bad that you don't care what she's made out of. Unfortunately, I do worry that this is a gateway to being a serial killer, but what can you do?
What I find most disturbing isn't that the paper-person exists, but that this guy seems extremely attentive to it. When's the last time you saw two people on a train facing each other while they talk? This guy is working hard to make sure this date goes well. I just hope that he doesn't bring up origami. That could be a sensitive subject.
