It sounds like this guy had pretty poor manners. Manners make the man, so they say...
Whether you're traveling, or visiting a friend, or dining in a restaurant, how you conduct yourself says a lot about yourself. I find rude, demanding, or otherwise obnoxious people to simply possess poor manners. Some level of self-awareness is necessary to possess manners, and it can go a long way towards maintaining, improving, or otherwise alienating your friends, acquaintances, or simply those in proximity to you.
Sorry you had to endure this callous person, particularly in your own home. That is the worst.
Oh, no worries. I told my friends not to bring anyone to my place unless I get to meet them outside or see their profiles first. It saves me a lot of disappointment.
