I am prompted to write on envy because I look at my daughter’s skin and wish mine was as smooth and unmarked, with far less cartographic detail of my life’s journey. Sometimes I wonder if people look at that wrinkle and wonder at what vicissitude might have caused it. Or those freckles there and think ‘she spends far too much time in the sun.’ Because that is inevitably the kind of thing that I muse upon when I look at someone’s face or hands. What caused that? What happened there?
