There were stories only shared between grandmother and granddaughter, because they were permitted to be alone without the power play of mother and daughter. In male dominated societies neither the elder nor the child is considered to be of importance. So they are allowed to whisper to each other and tell the stories that are not meant for male ears.
The nuance of the story would be memorized. The shape of the hand. The sensation of the cool air. The breeze between the legs. The subtle intake of breath in the nostrils will be noticed, and one’s organic reactions to the sudden turns of the stories. Such stories were never told among men, for fear that the veil would be ripped apart and men would realize the futility, the meaninglessness of their ways.
