The Obama's are also very affectionate people.
This is just my point of view, but, it is my interpretation that when Michelle visited Great Britain, she was received as a lady that could project a role model to their minorities, hence, the open affection between her and the Queen. I thought it was pure genius on the part of Queen Elizabeth to show case Michelle.
I also believe Michelle is very sensitive to people's perceptions of their own lives and limitations.
I believe the tears we witnessed in attending a school in Great Britain related to the fact there is still socio-economic lines in Great Britain the Royal Family is unable to influence. She was probably touched by the fact their is still segregation that needs to have walls removed. I could be wrong, but, I think Michelle is very sensitive to separation of people and their social influence when it is based by race or gender.
Katie knows what it is to be a wife, mother and career girl. She knows it has to strike a fine balance. The difference between Katie Couric and Michelle Obama is the visibility of The First Lady and her influence in venues that directly effective the lives of Americans and their allies.
I think she is great. We have longed for a 'modern and vital' First Lady AND her First Daughters. They are a refreshing moment in everyone's day.
I am sure Washington, DC is finding the gap between beinging the 'seat' of the nation's capital and the home to residents filled with the overt presence of the newest of residents, The Obamas.
With the President, First Lady, the girls and Bo out and about in SAFE venues of involvment and exposure, the city of DC will be exposing its needs to a federal watchfulness it hasn't received before. Barak Obama is an experienced community organizer with instinctful watchfulness to community dynamics. I have no doubt when he and the family venture out to the public sphere of their lives, they have a watchful eye on how well the 'city' of DC is doing. Perhaps, the lack of influence lost by 'the city of DC' at the federal level will finally find a helping hand from its latest residents in filling in 'the power' void.
