I don't think he does it on purpose, I just don't think he views it as badly as I do? I know after his friend left, I said to him, "next time any of your friends stay the night, I want them gone by noon. Not just awake, but out of my house." He agreed. He also agreed with me that his friend's diet was awful, which is probably what is causing all his stomach issues. So he's coming around, but he's still not as shitlordy as me.
