The president was talking education when the 11 year-old let out a serious yawn.

Fatigue or boredom aside, Sasha did manage to keep clapping for her dad.
This is not the first time the youngest Obama daughter has yawned while listening to her father. In 2008, she yawned during the Democratic National Convention with her head on her mom's lap, USA Today reported.
Sasha also made headlines Sunday, when her dad was officially sworn in. Afterward, she congratulated him by saying, "Good job, Dad. You didn't mess up."
