I like to people watch. I sit at a restaurant and quietly watch people interact. I am just interested in people. :)
That's funny.  I do the same thing!  I love wondering what people are doing or where they come from!
I hate to admit it but I also like to eavesdrop. lol
Sometimes it is hard to stop listening when someone is saying something interesting to someone else.  I have been there and done that!
Yeah for some people watching is a hobby but for most it is just a subconscious activity that they do everyday.
I wonder what the underlying reason is for that particular type of behavior.  I guess it is just curiosity, right?
Yeah I think so. Absurbing their environment I guess. But people watching is not to be confused with naturalistic observation.
What is the difference between the 2?
Naturalistic observation is a scientific term and use for that purpose and just regular people watching is a casual activity where people find themselves interested in others and what they are doing.
