Not only clever lines are needed to pick up chicks but reading their body language seems really important. I've seen many girls who are possibly into me yet they just can't seem to confide in and say out loud like it is forbidden by law or something. So I figured I need to put a little effort and read their body languages.

Today at work, there was a woman sitting next to me and this was the sitting positions

Guy - Her – Me. (There were no partitions between all of us)

When this woman comes back to her table, she pulls a chair, as she sits down her body was towards me. (Happened twice) Does this mean she's more interested in me than the guy sat next to her? How can I become the mastermind of body language?
