Have you had to ask if you have accidentally flashed someone?

I think I have, and it makes me a little worried, this morning at a visit with Addie to a senior citizen in Ealing. I didn't see him cringe, or react at all.

The postman delivered this heavy box containing the footstool he had ordered, and when I bent down to pick it up, I forgot I was not wearing panties. I didn't realize immediately, but when he thanked me quite profusely as we went to leave, it occurred to me as having been likely!

Now I am pretty certain that I accidently flashed him!
