Yep, it finally happened. I was working at home on my PC, naked as usual, or at least naked as the temperature permits. The doorbell rang, and the dog went bananas, (also as usual). Calming the dog down, I opened the front door, and a smartly dressed woman stood there looking slightly surprised at the naked man in the door frame. I said: "hello, and I'm sorry about the dog noise, she'll calm down in a minute. What can I do for you?"
She slightly stammered, but was otherwise quite calm: "Uhm, well, I wonder if you might be interested in reading this?" and held out a small pamphlet towards me. as I read "Der Wachturm" across the top and "... Jehovahs ..." underneath. (I live in Bavaria, Germany, btw.) Hmmm, I frowned, not being a particularly religious person myself, but took the pamphlet, being polite and saying "thank you", as you do.
I smiled inwardly as I realized I'd just unexpectedly confronted a Jehovah's witness with my naked body, (which is one of the classic fun naturist-with-non-naturist scenarios one hears about), and wondered what was our next move. She took the initiative, by looking me up and down, and saying: "Perhaps you might read the pamphlet through, and I'll come back in a couple of weeks and we can discuss any questions you might have?"
I replied with something like: "Sure, whatever, have a nice afternoon", as she smiled, perhaps a little uncertainly, before turning and walking away. I waved her goodbye pleasantly and closed the door. Perhaps she'll come back, perhaps not. Either way, it was a pleasant enough encounter, and as a bonus I have some free fire-lighting material, (which is where most of the advertising which comes through my post goes).
