First Lady Michelle Obama is in London where she met with American athletes Friday morning to share a few words.
"You never know who you are inspiring, I mean you just never know -- from a family like ours on the south side of Chicago to young athletes who are going to pick up a soccer ball, or start running after watching something that you all do. And I know from many of you, that's how you got here, watching someone else, so you never know who you are going to inspire."
The First Lady told the athletes how much the Olympics meant to her family while she was growing up -- especially to her father.
"My father wasn't able to walk without the assistance of crutches, but he retained his love of sports, truly. And the Olympics was a special time for him to watch amazing athletes of all abilities compete on the world stage. So these games especially affected our little house on the south side of Chicago. Every few years, these games bring pride, excitement and wonder to millions of people around the world."
Mrs. Obama will also be on hand tonight representing the United States at the Opening Ceremony.
