Char, this is a topic that I have often thought about. So many of us seem to confuse silence as acceptance.
People DO notice. They might not say anything at the time but you can bet they talk about us later. We are an extremely unique part of the population and they do notice.
I remember a time when my tenant walked into my kitchen while I was getting a drink. I was wearing a sheer pair of nude pantyhose under my shorts and tried to convince myself later that she couldn't have noticed. We talked for a few minutes and I realized that the reinforced toes of my nylons would have been a dead giveaway.
She has never said a word since about that incident; however, whenever she talks to me now, I see her discreetly glance down at my feet.
Her silence doesn't indicate acceptance. If anything it merely indicates politeness on her part.
