Non-Passable....

Ok: I do not understand. CDs are like everybody else. Some are dominant, some are submissive, some are introvert, some extrovert. But being non-passable, it seems to me is a like a person dressing up to be the Belle-of-the-Soiree and then declining every invitation to dance. I would certainly appreciate enlightenment. I do try to understand the desire to dress and be entirely gorgeous to some onlooker but is that to be a sort of tease....or an inability to open up and, in a manner an incapability to go all the way?
