People-watching

[1][2] 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.

[3] This includes speech in action, relationship interactions, body language, expressions, clothing, activities and crowd behaviours.

Eavesdropping may accompany the activity, as documented by the humorous blog Overheard in New York, though is not required.

[4] For some people, it is considered a hobby, but for many others, it is a subconscious activity they partake in every day without even realizing it.

[citation needed] People-watching is distinguished from naturalistic observation, a process used for scientific purposes, compared to people-watching as a casual activity, used for relaxation or inspiration for characters or characters' mannerisms in their own creative works.
