Michelle Obama gets real with kids at White House

First lady Michelle Obama was being grilled Thursday, one question after another by tireless interrogators.

She exposed that she likes playing tennis, cuddling with dog Bo and rooting for the Chicago Bears.

Her favorite book is Toni Morrison's "Song of Solomon." She likes the colors lavender and purple, and she favors the Yellow Oval Room in the family quarters and the Rose Garden.

Obama's questioners were kids visiting the White House for "Take Our Daughters and Sons to Work Day."

Among the children on hand were Austan Goolsbee's daughter, Aden, 10; and son, Addison, 7. Their father, on leave from the University of Chicago, leads the Council of Economic Advisers.

The first lady disclosed that Bo, their Portuguese water dog, thinks he's family. "Bo thinks he's a child," she said, noting that if her daughters Malia, 12, and Sasha, 9, are sitting on her lap, he'll barge in to dislodge them.

An 11-year-old girl asked Obama if being first lady had any disadvantages. You just can't walk out the front door and go to the store, Obama said, recalling the days when she drove, shopped for groceries and hit Target. "That would create a lot of problems for a lot of people. And it would be chaotic."

But difficulties are outweighed by the chance to tackle problems such as childhood obesity, she said. Another plus is meeting people like Beyonce, Willow Smith, Stevie Wonder and Paul McCartney.

An 11-year-old boy asked which she liked better, the White House or her old house?

She said Chicago remains home, but "this is where the girls go to school, this is where the majority of their friends are, this is where their dad works, this is where we live, so this has become home too."

About her hometown, she added: "We kind of avoid it in the winter because it's cold."
