I'm nearly always naked at home during the day. I answer the door nude to nudist visitors. And I keep a robe behind the door for other visitors. But yesterday a delivery man knocked the door so insistently that I just answered it while still naked. I half hid behind the door. That was no use as he had two big heavy parcels for me. I had to fling the door open and take each parcel in both hands, ono by one. Then I had to sign for them. The delivery man must have seen this before - he took it all in his stride as if nothing was out of the ordeinary
I only answer the door nude when one of my nudist friends arrive. In winter I keep a robe near the door and in summer, a pair of very small running shorts. There is a sign on the door that says - This is a nudist household. some nudity may seen.
