I people watch all the time. I just try to observe and figure rules from my observations. If person (A) does this, person (B) has a tendency to do that in response.
But, I have to watch from a distance. Up close or in person, it all gets washed away as I am overloaded with stimuli and cannot make connections on the fly. If they deviate from my "rules" that I observe, I am doubly lost.
Oddly enough, those that people consider to be "beautiful" bore me. Maybe too much symmetry to be noticeable? But, the odd face or body type with noticeable imperfections and asymmetry are interesting and attractive to me. And there are facial types that just freak me out. The big forehead/doll like face really bugs me. I find it attractive in art, but creepy beyond compare on real people.
For instance, my wife: She has a crooked smile that pulls to one side. But, most of all, when she smiles, I get it. She has those eyes that actually turn into upside down "U"s when she smiles. It's such a marked difference that I can notice it. Offset mouth, upside down 'U's for eyes...yep, she's happy. Ok...happy wife, happy life...or so I've heard.
Otherwise, unless someone has an extreme facial structure or expression, it's all a wash for me.
