New York (CNN)As part of the White House's annual Take Our Daughters and Sons to Work Day, First Lady Michelle Obama met with and fielded questions from children of Executive Office employees, local young people from the Boys and Girls Club and D.C. Child and Family Services.
During the question and answer portion, a young girl innocently posed Obama a daring question.
"How old are you?" she asked.
Obama hesitantly replied, "51."
But what wasn't seen was the young girl's immediate reaction to Obama's answer, which was off camera. It's obvious from the first lady's response, the young girl was making quite the expression.
"What's that look?" Obama pried.
"You look too young!" the girl exclaimed.
Obama instructed her staff to give the girl a mic for all the room to hear.
"You're too young for a 51 year old!" she repeated.
Obama gleefully had the young girl repeat this a few times before inviting the girl up on stage for a big hug. Her day is made.
