Motherhood sometimes seems to me like a sort of relay race, a journey whose purpose is to pass on the baton of life, all work and heat and hurry one minute and mere panting spectatorship the next; a team enterprise in which stardom is endlessly reconfigured, transferred. I see my daughter hurrying away from me, hurtling towards her future, and in that sight I recognise my ending, my frontier, the boundary of my life.
