I read somewhere once that crying defies scientific explanation. Tears are only meant to lubricate the eyes. There is no real reason for tear glands to overproduce tears at the behest of emotions. 

      I think we try to release the animal parts of us without losing our humanity. Because inside me is a beast that snarls, and growls, and strains toward freedom, toward Tobias, and above all, toward life. And as hard as I try, I cannot kill it. 

    So I sob into my hands instead.
