I am pretty sure that I've watched a TV documentary about people and their ability to read other people's faces and body language. There were a lot of small pieces of information I picked up.
I like reading people. I think I'm pretty good at it. I don't always act intelligently to the information I learn (aka daring someone to hit me when they're angry) but I at least knew what might be coming. What I don't seem to be able to master is knowing or reading when someone "tips" from positive to negative. I think I just want to believe all people are good so badly that I ignore those tell tale signs.
Thankfully lack to my dating life I've not needed to use those skills. Mostly I use the to gage how frustrated people at work are. I know for a fact that my trainer was unhappy with me friday. I came in late from a doctor's appointment and then proceeded to work at a snail's pace the rest of the day. I refused to even take some of her calls, which I typically do. Her face was slack and her shoulders were "tight", but she didn't say a word.
I've noticed that typically people in customer service jobs tend to make indirect eye contact. Looking just to the right, left or above your eyes. There is a smile on their face, but they definately don't want to extend the contact hey have with you. One exception to that is at the Pie Shop. I've been going there so long that the waitresses will chime in on the conversations I have with my retired friends. They are also good readers and some times I'll go there for lunch and they'll know it's a comfort food kind of day. Extra fries magically appear on my plate of grilled cheese.
Public transit is a completely different story. People will go to extremes to avoid both eye and physical contact. The way they hunch their shoulders and stare blankly out the window are defensive postures aimed at keeping you out. If you really want to mess with them, go sit in the seat next to them when clearly there are empty seats where you can have "cushion" of other empty seats.
The other thing is the hands. Watch them, not blatantly, but watch them. People under duress (stress or nerves) will be practically unable to keep them still. I have also observed someone "flutter" their hands in front of them while talking in what I can only describe as a protective gesture when defending a point of view. Clearly they felt challenged and a little bit insecure in their opinion.
Am I the only one who does this?
No...me too. I sometimes just love grabbing a coffee in the local shopping centre and watching people as they go about their day to day rituals. It can be fairly obvious who is having a good day and who is having a crappy one. My newest job and previous employment as a security/bouncer give me plenty of opportunity to watch people. It was always interesting even as a carpenter. Watching the customers shoulders drop as I removed their kitchen as everything they were used to was removed and that comfortable space looked totally foreign to them. Then watching their expression completely change as the new Kitchen took shape. Watching the excitement build as I got nearer to finishing. People are so much fun.
