My new door sign

During the past few weeks I have had multiple sales persons come to my door trying to get me to buy whatever it is they are selling. That, I can put up with if it is an every now and then thing.
However the past few weeks have seen Jehovah's at my door every Friday too. I'm unimpressed they wish to convert me from my sinful ways...I quite like them. They either laugh at me when I have to end up telling them I do not believe in any religion or god or they look at me with pity. I have always been polite to them but I have simply had enough. It comes down to this...I don't go door knocking to tell people about my Atheism so why do people feel it's OK to come to my home and tell me about their religion?. So I felt it necessary to stick a sign on the door. They haven't knocked this week.
