I just bought this sign for my door because I am so sick of these assholes invading my life every other week, often while I am napping. I really hope they take heed. How is this considered okay, to come banging on someone's door, unexpected, not even considering what kind of hours the occupants might keep? I don't even understand it, does this method ever actually work? I mean, people know churches exist, right? Are there really such weak minded individuals out there who just take up any religion that happens to come knocking at their door?
