President Obama gave his farewell speech to the nation Tuesday night, and it included an emotional tribute to his wife, Michelle, and daughters Malia and Sasha. "Of all that I have done in my life, I am most proud to be your dad," he told the girls—though only one of them was in the audience to hear it live. While Malia, 18, wiped away tears during her dad's words, 15-year-old Sasha was noticeably absent. The Internet started "freaking out," USA Today notes, spurring the hashtag #whereissasha, per CNN, with wild speculation ranging from the first daughter being on the hunt for Donald Trump's tax returns to her "blocking the driveway to the White House." The actual reason was decidedly undramatic: The high school sophomore had a test at the Sidwell Friends School on Wednesday morning, per a senior administration official. (More Sasha Obama stories.)
