When you work out of your home, you get to meet the many people who you would otherwise only know from the things they hang on your doorknob. They are usually startled when an actual person answers their quiet knock. I invariably open the door just as they are hanging something on the doorknob. In order to keep their lives at least a little interesting, when someone comes by with a religious tract or invitation to save the world through prayer to some deity, I always politely tell them I’m an atheist. Then I smile sweetly and thank them for coming by.
The look of horror and confusion on their faces is priceless. And I know I’ve given them something to discuss that will keep them from being bored as they go door to door.
I view it as a win-win.
