One of my friends let them come into his house, then talked to them for about an hour, pretending to be interested. At the end he simply said he didn't want to convert and they left, having wasted a very long time.Shine-osophical said:EDIT: You know those religious people who go door knocking??? My brother did an awesome thing which has stopped them coming around for over 5 years now. He let them talk and talk and talk (for like ten+ minutes), and then, at the end, he said, 'have you considered buddhism' (he isn't buddhist but he spent a few months learning about buddhism so he knew his stuff). Then he spent 20 minutes telling them all about buddhism. AND IT WORKED!!!
I'm glad I live somewhere they wouldn't bother to come to.
