President Barack Obama may have used his farewell speech to praise his two daughters, Malia and Sasha, but one of them wasn’t even there!

After eight years in office, Obama bid goodbye to the White House with a heartfelt ceremony in his hometown of Chicago. Watch part of his emotional speech in the video above.

His wife, Michelle, and eldest child, Malia, 18, stood proudly by his side as he thanked his family for their unbreakable support.

However, during the hour-long speech he never addressed his 15-year-old’s absence, causing social media to immediately begin speculating.

The hashtag #whereissasha began trending and Twitter was rife with funny GIFs and memes about the missing Obama daughter.

But it turns out she had a very good reason for skipping her dad’s big farewell: She had an exam in the morning.

CBS News White House correspondent Mark Knoller tweeted the answer, putting many minds at rest.

“Where was Sasha?” he wrote. “WH official says she stayed in DC tonight because she has an exam at school tomorrow morning.”

Sasha is a sophomore at Washington, D.C., private school Sidwell Friends.
