People-watching or crowd watching is the act of observing people and their interactions in public. It involves picking up on idiosyncrasies to try to interpret or guess at another person's story, interactions, and relationships with the limited details they have. This includes speech in action, relationship interactions, body language, expressions, clothing, activities and crowd behaviours. Eavesdropping may accompany the activity, as documented by the humor blog Overheard in New York, though is not required.
