It seems an odd affectation she has. Their body language couldn't be worse. She's almost repulsed when he hugs her. Like she can barely tolerate being there. Weird.
(A little off-topic but I have to share...Only freepers would understand) Yesterday I was forced to walk down Hollywood Blvd. on my way to a car dealer. Near Hollywood and Vine there was a long line outside a theater with tons of news media present. As I got closer I realized that this was a Kerry fundraiser for with his daughter as the main event. There were all these squeaky clean, orderly 18-20 types all dressed in Kerry gear, clearly thrilled to be even remotely close Kerry's daughter (And it wasn't even the see-thru Cannes daughter). The whole thing was very, very creepy and depressing!
