Michelle Obama gave a few students the surprise of a lifetime when she unexpectedly visited Tuesday a high school near the U.S. capitol. Students at Ballou STAY High School in southeast Washington were expecting a visit from the new chancellor of D.C. public schools, Antawn Wilson, when suddenly the former first lady arrived, according to reports.

During her unannounced visit, Obama met with students, marking her first official outing since her husband, former President Barak Obama, left office in January. It’s unclear what Michelle Obama discussed with students, but she reportedly met with about 14 high schoolers privately.

Michelle Obama, who was a major advocate for education during her tenure at the White House, has a reputation for popping up on students unexpectedly. Back in September 2016, Michelle Obama surprised students at Howard University along with the host of NBC’s “Late Night” show, Seth Meyers. During that visit, she answered questions and gave students advice on how to succeed during college and long after graduation while encouraging them to “step out of your comfort zones and soar.”

In March 2015, she gave a visit to school children at Watkins Elementary School and John Burroughs Elementary School in D.C., during which she spoke to kids about the importance of healthy eating, something she’s also been incredibly passionate about, while helping them tend their community garden.

Back in 2014, the former first lady shocked high schoolers when she gave hugs to the class of 2015 seniors at Capital City Public Charter School following their annual College March, during which graduating seniors parade through the hallways before mailing off their college applications.

While many of the initiatives Michelle Obama’s launched during her time as first lady stemmed around childhood development and education in the states, she was also a big advocate for educational programs in other countries too. Her LetGirlsLearn program, which was created in 2015 in conjunction with the Department of State, the U.S. Agency for International Development, the Peace Corps, the U.S. Department of Agriculture, the U.S. Department of Labor, the U.S. President’s Emergency Fund for AIDS and the Millennium Challenge Corporation is aimed at expanding educational resources for girls living predominately in countries with a low rate of educated young females.
