Today, on the 70th anniversary of the liberation of Auschwitz, the world remembers the millions of victims of the Holocaust. Nazi Germany murdered six million Jews, homosexuals, gypsies, and communists.

Elizabeth Wilk was one of the survivors.

Later today, she will speak at the Israeli Embassy, before President Obama, and in three minutes, she will tell her story to him and the world. Before she left for the Embassy, she asked me to listen to her story and to help her with her nerves.

The anchor of memory is emotion. It's helped along, in this case, by the masterful use of simple sentences, which Elizabeth wrote.

As she told me her story, I was flooded with images of people, places, things, and events, most of whom Elizabeth never mentions. But they're all there, behind every word, every pause. They lived in the silences between sentences.

When she finished, she said to me, "That's it. There's nothing more to say."

She was right.
