Bush body language read in photo with Tina Turner

If you go to
You will see a group photo with famous people including Robert Redford and Tina Turner and
As a body language expert who works with law enforcement and the media I do photo body language reads. Looking at this, I find it interesting that Bush has chosen not to touch Tina Turner or his wife. This communicates his desire to single himself out in this group of illustrious people. The lack of touch, intimate space or leaning towards anyone when placed in the front and center postion says I am seperate and above.
