On this anniversary, I recall the time I happened to come face-to-face with JFK, while he was in the White House and I was barely in kindergarten.
My family was taking the standard White House tour, when we came to a room with a curtain blocking the entrance. The guide indicated that the president was in a meeting behind that curtain.
Being a curious child, and standing very near one end of the curtain, I pulled the corner back slightly and peeked in. The president noticed me - a little girl Caroline's age - and he smiled and waved.
He radiated friendliness and charm. That day, he became my first crush.
I will never forget that brief moment when I learned at a very young age that great people are human and can be so down-to-earth.
And I think that lesson emboldens me in my human rights work today.
