This is an observation.  I watch a number of shows regularly--NCIS, Burn Notice, sometime Covert Affairs.  I watch the characters carefully, and I learn social skills from them.  I make a point of watching, say, how the NCIS team spars with suspects in interrogation.  I watch shows where law enforcement people have to know how to read suspects and criminals.  I didn't know I had Asperger's in my twenties and thirties, but I knew I was terrible at picking up unspoken social cues and terrible at reading people.  So I worked at teaching myself those skills, and one thing I've found useful is watching TV, and also when I go to the movies, I do the same thing.  I observe the characters and the action.  I suggest it for learning to read people.
