Wow. Is there a sign on your door that lists out these 'rules' of proper socialization during visits? I'm sure you also have limits on having a third drink: 'not polite'. Telling dirty jokes: 'not polite'. What about watching a movie together with friends, that kills conversation! NOT POLITE!
I imagine a visit to your house being a nice setting at a dining room table with a white tablecloth, sipping tea, quietly discussing the important issues of people's lives and matters of international importance.
Meanwhile, my girlfriend and I, along with the couple we invited over that we've known for years, are drinking wine and beer, telling jokes, and occasionally turning up a song that's playing so we can all sing along and dance to it.
Different worlds
