I don't know the women in this photo. I took it while having dinner at a restaurant last summer. It tells a story of two friends enjoying a pleasant summer dinner.
When I cropped it to remove the dinner partner I think it tells a different story. Here we don't know nearly so much. Is she dining alone? Is she waiting for a friend who is coming later? There is something about silhouettes that creates an air of mystery.
