Leaning Forward (goes with AmySit7Cjpg)
By leaning forward, you appear larger and more intimate. When we are with someone we like, we tend to touch him or reach out as if to touch him or lean forward or touch ourselves. Amy combines a forward lean with a smile, but creates an arm cross. Later however…

Add A Head Tilt (AmySit5Cjpg)
she adds a head tilt and loosens the arm barrier. She keeps the smile and then…

And A Wrist Flash (AmySit6Cjpg)
she removes the arm barrier even more and adds a wrist flash.

Now she is using:
 1. Lean Forward
 2. Smile
 3. Head Tilt
 4. Wrist Flash  

Compare the photos. Can you see how Amy is using nonverbal signals to develop her relationship, step by step?
