NATIONAL BRIEFING / AND FINALLY . . .

First Lady Michelle Obama’s mother summed up her life at the White House in one word: wonderful.

Marian Robinson says the mansion is “much bigger than anything I’ve ever been accustomed to” and has “lots of people to take care of you.” Granddaughters Malia and Sasha are growing up so fast that she’s beginning to feel “left out.”

Robinson, 71, provided a glimpse of her life at 1600 Pennsylvania Ave. after she read to a group of elementary school students in Washington’s Maryland suburbs as part of a summer reading series.

President Obama’s mother-in-law took more than a dozen questions from the students, including whether she is rich.

“No, I am not rich,” Robinson told the boy who asked. “But that just lets you know that you just need to earn enough money to pay your way and you can still be happy and still be in a place where you never thought you would be.”

She said Malia, 11, and Sasha, 8, don’t watch much TV.

“But they are at an age now where they’d rather read books or play games with themselves, so Grandma is beginning to feel left out,” she said. “I spend a little time with them, but they’re growing up now.”

Overall, Robinson said, hers is a wonderful life.

“I’m able to take care of my two grandchildren when their mother’s busy, and she is pretty busy these days, and I am glad to be taking care of them. So my life is wonderful.”
