Blurry Subject, Crisp Background

Focus itself implies that the lens has been focused on a certain point, if the depth of field is shallow enough then objects outside that point will become blurry. You can also make things blurry if you are moving or they are moving and the shutter speed isn't fast enough.

Though I did mention focus in the description, the title says "Blurry" so for the purposes of this contest, I will be allowing photos in which the subject is simply blurry because of motion blur, and not necessarily out of focus.
