Reading / communicating with body language is an art, much like learning to play a musical instrument or speaking a language. It takes study, practice and feedback to truly learn it well. While a book / written list of words cannot replace the actual body language, here are some general universal cues, just a few that came to mind:
Arms crossed: closed / defensive Hand on chin: thinking / contemplation Leaning in / touching you: signs of interest
Usually, it is a group of cues that forms a picture of what someone is really thinking. An individual cue by itself can be unreliable and should be taken with a grain of salt.
