I have a mate staying in my spare room who's gay. It's great tbh; I haven't had to clean the bathroom or kitchen in 5 months as it's constantly clean. He's a damn good chef too and a computer genius.
He's picked up the rules quite quickly too:
1 - Don't speak to me before I've had a smoke and a cuppa in the morning unless you want to be told where exactly to f-off to. I'm not a morning person!
2 - We look with our eyes, not with our hands. i.e - touch the NeoGeo / Dreamcast games and there'll be trouble. That said, he's up for Last Blade sessions.
