It is as though some old part of yourself wakes up in you, terrified, useless in the life you have, its skills and habits destructive but intact, and what is left of the present you, the person you have become, wilts and shrivels in sadness or despair: the person you have become is only a thin shell over this other, more electric and endangered self. The strongest, the least digested parts of your experience can rise up and put you back where you were when they occurred; all the rest of you stands back and weeps.
