On Today's episode of Oprah, they featured people keeping Dr. King's dream alive. One story was about two unlikely cousins.
Vy, An African-American artist from Harlem found she and Marion, a white elderly cattle rancher from Missouri were cousins. When he first contacted her, he did not know she was African-American. It's unclear from the show or the article whether he was made aware of that, but there's footage of them meeting at the airport for the first time and it appears that's when he first learns of their differences. He throws down his coat, gives her a big bear hug and says in an astonished tone, "Cousins? Isn't that beautiful!"
That left me breathless and in tears. Their differences could have been startling or shocking or even disconcerting, but no, he found their differences and their ties beautiful. How wonderful!
