There's a 25-year-old woman in Alabama named Hayden Hatfield Ryals. And while she was at Auburn University a few years ago, she decided to become a bone marrow donor through a charity called Be The Match.
All you do is register online . . . swab the inside of your cheek . . . and mail it in. Then they contact you if they ever find a match who needs a bone marrow transplant.
In Hayden's case, they did find someone. About a year after she signed up, they called her about a one-year-old girl in Ventura, California who had leukemia.
So Hayden took the next step . . . donated some of her bone marrow . . . and it saved the girl's life.
Her name is Skye, and she's 3 years old now. Hayden says she thinks of her as family.
But they didn't actually get to meet in person until last month . . . when Skye and her parents flew out to Alabama for Hayden's WEDDING after she asked Skye to be the flower girl.
