Why do you get out of bed in the morning?

This was one of my favorite images before I ever released the shutter. I found this question on the underside of a bridge while I was out on a walk with a friend of mine. I appreciate graffiti when it is done well but whoever did this was more of a philosophical deviant than an artistic one. Such an important question written in a place that is isn't likely to be seen often, or by many people.
