A glimpse of Anne Frank, from a window

The Anne Frank House has uploaded a video that provides a fleeting glimpse of Anne Frank on July 22, 1941, roughly a year before she went into hiding with her family. The video shows Anne leaning out of the second-floor window of her Amsterdam home to see her neighbor, who is getting married.
The National Post reports that the video has become something of an internet sensation since it was uploaded this past Wednesday. “Nine seconds into the film,” the paper adds, “a 13-year-old Anne is seen leaning out of a second-floor window, smiling and looking down at the street to see the bride and groom.” How utterly, utterly sad.
