I love the way this photograph acknowledges the world around itself. There are three couples more or less contained in the center of the image but on the right hand side there is another couple only partially visible who are facing out of the image, so they are looking at or talking to someone outside of the image, or just dancing. And on the left side there is parts of someone's foot visible proving that there are more people outside of the image. It seems to me that many photographers try to center a "subject" and go to great pains to eliminate any hint that there is more going on outside the frame.
I am curious about the term Taxi in the title.
