Extended Metaphor Madness -- "Tonight I Feel Like a Library Book"

Tonight I feel like a library book. Still sequestered in a book bag, waiting for some sort of utilization. I might be read. Maybe I'll be used as a door stopper. If I'm big enough, maybe a booster seat. I can hear that there are things going on. Sometimes I get close enough to the walls that I can smell the outside, and light calls the softest attention, a siren several city blocks away, to the edges of things that surround me. If I just let my mind rest, willing the creation of some sort of reality, I am wherever I need to be. But when I remember that I am here, I remember that I am still only just here. I want to be read. But really, I just want to get out of this bag.
