Do You Observe People As A Hobby Or Interest?

[zanzibarjones 1]

I have this little hobby, I guess you would call it, about watching people. Not in a perverted kind of way, but more to watch their body language and mannerisms. I do it, so I can get a better idea of how to approach people, how to speak to them so that they understand me better, and how to stay away from those who do not want to be bothered.You can tell a lot from people by just watching them. Am I the only one who does this? If not, what have you discovered about people?
