I had two visits in a single day from strangers. You know the kind. Magazine subscription salesmen, representatives of various religious sects, college kids trying to sell sets of books so they can have their semester in Rome. My question is, how do you deal with this? I don't know anybody who actually sits around hoping for a total stranger to knock on their door and interrupt their life, attempting to sell them something they had no particular interest in. I have a difficult time being outright rude to people, but it seems like you all but have to in order to get rid of some of these people. Any humorous or clever ways of dealing with this?
