I suppose with Mrs. Bruni being the wife of a leader and Michelle’s position you would think there are some things they both could relate to. There are very few people who could relate to that kind of stress of being under the microscope.
While it could be considered indiscreet to broadcast personal conversations, it is obvious that Mrs. Bruni could care less about Mrs. Obama's reaction to her quoted comments. As far as I'm concerned, the sum total end-result, is a big "so what?" especially because Mrs. Obama doesn't deserve much in the way of respect.
