“Malia and Sasha, eight years ago on a cold November day, we greeted you on the steps of the White House. We saw both the light and wariness in your eyes as you gazed at your new home,” they wrote.

The Bush sisters recalled taking time off from work and traveling back to Washington to play tour guide to the young girls who would succeed them as the “First Children.”

“The four of us wandered the majestic halls of the house you had no choice but to move in to,” they write.

“When you slid down the banister of the solarium, just as we had done as 8-year-olds and again as 20-year-olds chasing our youth,your joy and laughter were contagious.”

But perhaps most exciting for the young Obama girls: The not-so-secret perks of living in their new home. Among them, a private bowling alley and movie theater.

"It's just amazing how fast eight years go by and how they've become these really unbelievable women and we just wanted to make sure they knew," she said.
