Today's the day for Malia, 10, and Sasha, 7, their first at the ultra-elite Sidwell Friends School.
And, reports CBS News correspondent Kimbelry Dozier, while their attendance will be on the lips of everyone, that's likely to die down quickly: Sidwell students tend to take the presence of kids of the rich, famous and powerful very much in stride, since so many of them fit that category, too.
It's the same school once attended by former first lady Nancy Reagan, and by former first daughter Chelsea Clinton.
"In every grade at Sidwell, you have the children of diplomats and of wealthy parents, but you really don't notice a difference," says former Sidwell student Delaney Kempner.
"I think everyone's pretty excited the that the Obamas are coming," concedes Sidwell senior Piera Kempner, Delaney's sister.
She says the Obama buzz is all over campus, but it's not likely to last much longer than recess.
"Students, especially in the upper school who don't go to school in the exact same building, will want to catch a glimpse of them in the lunchroom, for example, but I really do think it'll settle down," Piera observed.
That, says Dozier, may be one of the main reasons the Obamas picked Sidwell -- the students are kind of used to this.
And the school's two campuses are just about custom-made for kids of the rich and famous.
The upper campus is ringed by fences, and the lower school is geographically out of the fray, set way back.
"Reliable Source" columnist Amy Argetsinger of the Washington Post says, "At a public school, it would have been that much easier for ... photographers to camp out across the street to try to get pictures of them on a playground. At Sidwell Friends, you've got a long driveway, a lot of trees -- you've got a real buffer of privacy."
And that, says Dozier, enables kids to be kids, and power politics of the playground to assert their natural supremacy over parental ones.
"We have our own politics going on in the hallways," remarked Aliza Kempner, Delaney and Pierra's sister.
Sasha and Malia will have to learn how best to take charge and fit in, just like their dad, concluded Dozier.
