I realized that our time in the White House would form the foundation for who they would become and how well we managed this experience could truly make or break them. That is what Barack and I think about every day as we try to guide and protect our girls through the challenges of this unusual life in the spotlight, how we urge them to ignore those who question their father's citizenship or faith. How we insist that the hateful language they hear from public figures on TV does not represent the true spirit of this country. How we explain that when someone is cruel or acts like a bully, you don't stoop to their level. No, our motto is, when they go low, we go high.
