Well, while I'm pointing things out......... if you watch the clip Fox is showing as the First Couple is leaving the Texas ball, notice how they are holding hands, and then let go while the President goes back to greet someone, and Laura puts her hand inside his upper arm, and lets it slid down his arm to hold his other hand.
It's a neat technique she uses to keep 'in touch' with him...........methinks Laura's as much of a romantic as I am! :o)
