'The word "Mom" is familiar and it hides a plea: Please look after me. Please stop yelling at me and stroke my head; please be on my side, whether I'm right or wrong. You never stopped calling her Mom. Even now, when Mom's missing. When you call out "Mom," you want to believe that she's healthy. That Mom is strong. That Mom isn't fazed by anything. That Mom is the person you want to call whenever you despair about something in this city.'
