In this mob of I's inside, which one is me? Hear me out. I know I'm wandering, but don't start putting a lid on this racket. No telling what I'll do then. Every moment I'm thrown by your story. One moment it's happy, and I'm singing. One moment it's sad, and I'm weeping. It turns bitter, and I pull away. But then you spill a little grace, and just like that, I'm all light. It's not so bad, this arrangement, actually.
