Hand on the shoulder

In the dream I am younger, in a place similar to a school. Lots of other girls are also moving from place to place within a building. As I pass through a doorway an older man rests his hand briefly on the back of my shoulder. I keep my gaze forward, do not look back at him, but do not move any faster. I accept it. It is a gesture that feels complex, it is caring, quite intimate but also somehow like a selection.
