Unexceptional non-portrait

I didn't really take this as a portrait - I used the man to add to the composition of the magenta bench and the yellow window frames. I've cropped the photo to make it look more like a portrait, which is cheating really! Anyway, the poor man looks self-conscious and this photo doesn't tell you much more about him other than that he reads books and doesn't wear laces in his sneakers! I took it when using my DSLR for the first time with it set on Auto - hence no depth of field. Why am I posting it on my blog - well, I guess it's an example of a snapshot which doesn't constitute being a portrait!
