Nice job!

Once I've said "atheist" they don't pay me any attention and launch into their pitch anyway.

When they give me a chance reply, they hang their head in shame and wander away to the next house.

That's a nice exchange. Most of mine go that way but sometimes they still want me to "look at the trees."

You just wasted a big opportunity to convert them and help the humanity.

I will join in with the "well done" bunch......spread peace, not anger.....after all.. I was once as mis-guided as they......tomorrow they might be allies.

It would be nice if they were all that respectful of others! Most of the ones I talk to won't stop talking or accepting that I'm not interested. They continue to harangue until I slam the door or get irritated. I try not to, but fail often.

That's great. I always try to start that way, but I've never had them take no for an answer. Maybe you can teach a class

You indeed struck a rarity on that one.
Usually, in my experience, once being an Atheist is mentioned, they get very uppity/condescending/confronting,etc, and even, at times, aggressive even though I've been quiet, calm, courteous and respectful.
