[Serious] What is the most disrespectful thing a guest ever did in your home?

A friend projectile vomited all over the floor outside my roommates bedroom and just left it. I was completely unaware of the incident and it happened in a part of the house where I didn't go very often. The roommate was this really sweet, shy guy that never wanted to start any trouble. After a few days of walking around it, he finally approached me and was like, "Hey, uh, do you think you could clean that vomit up when you get a chance?" I was completely mortified. It's entirely possible that my friend had blacked out and not remembered after the fact, but still. I feel like she must have been conscious enough to at least let me know when it actually happened. Vomiting usually brings you back to reality pretty quickly in my experience.
