There, she shared how Malia and Sasha Obama -- 18 and 15 respectively -- bid farewell to their home of eight years. According to the first lady, they hosted a slumber party with friends, pizza and chicken nuggets.

"They had a sleepover, because of course on Inauguration Day, because my girls are so normal, they're like, 'Well, eight girls are gonna be sleeping here because it's our last time, and we want pizza and we want nuggets.' And it's like, really?," Michelle Obama said during the Thursday conference.

In reflecting on the girls' last night before Trump's inauguration, Obama said it was difficult for the girls to say goodbye to the White House.

"So that moment of transition, right before the doors opened and we welcomed in the new family, our kids were leaving out the back door in tears, saying goodbye to people," Obama said.

Obama joked that she had to maintain good face while welcoming the Trump family into the White House.

"I didn't want to have tears in my eyes because people would swear I was crying because of the new president," she said.

Obama also shared a funny note when reflecting on the Obama family's life outside of the White House.

"Friends are surprised I answer the door now," she explained, while also sharing that the Obama family's two furry members, dogs Bo and Sunny, have never even "heard a doorbell."
