City dwellers are instructed to ignore anyone who looks or behaves oddly

Evidence

Keep oneself aloof. Avoid attending (unless one can do so from a safe distance) to anyone who either looks or behaves “oddly.” When fleeing is not possible, act as if nothing peculiar were going on. Do nothing to suggest to the person in question that he or she is not quite “normal.” — Lyn H. Lofland, World of Strangers_ Order and Action in…, 920
