One way to establish rapport with a woman and to begin the process of developing chemistry is mirroring.
Pay attention to how she is positioned.
Which way is she leaning? Which way are her legs crossed? Is she leaning forward or backward? Carefully begin to start putting your body in a similar position she is in.
Try to mimic her body positioning as closely as possible (without looking like a woman).
Don't make this too obvious.
As you try it you'll see that it's not very hard to do.
Then pay attention to shifts in her body movement.
As she shifts position, you shift position.
This will subconsciously begin to develop a bond with you and stimulate her level of attraction to you.
Now start to change your position here and there.
See if she follows.
If she starts to follow your positioning changes, keep making them.
Just casually shift positions.
If you try it for a little while and she's not following you, go back to mirroring her positioning again.
Keep that going for a while and then try to get her to change along with you again.
This will begin to establish you as a leader.
While she unknowingly follows your body positioning she'll subconsciously begin to see you as the leader of the situation.
If you can't get her to follow your positioning - don't worry about it.
Just go back to mirroring her.
This will be effective enough and will make her believe that you two are on the same wave length.
