All, how would you handle the person who entered your open door while you were hosting a party? My guess is that if the 'guest' was gracious, polite and interested, (and interesting! Don't forget the obligation to be interesting.) he or she would be allowed to remain, perhaps even welcomed.

However, if the 'guest' smoked indoors when no one else did or ground a cigarette into the carpet or was rude or obnoxious or insulting to you or your friends, s/he would soon be hustled out the door.
