I understand her fear and it saddens me that millions of people feel it so often. The problem, however, is that if one feels fear of all people all the time, there is no signal reserved for the times when it’s really needed. A man who gets into the elevator on another floor (and hence wasn’t following her), a man who gives her no undue attention, who presses a button for a floor other than the one she has selected, who is dressed appropriately, who is calm, who stands a suitable distance from her, is not likely to hurt her without giving some signal. Fear of him is a waste, so don’t create it.
