To Rhys, my husband, I suspect there aren't enough thankyous for all that's to come. I've learnt and loved so much because of you—the way you slow your pace to keep company with the slowest walker; the way you sit in silence considering a question with care before you respond; and for all you are to our family, including the dad jokes, the music, the calm sea. To our boys, Elliott, Luka, and Sacha, for the electricity and brightly coloured cloaks you've brought to our lives, thank you. To my family and friends, thank you, but especially to Amiy, my mum, Prithiva Ferne Rajanayagam, for the visible support and for all the invisible support that makes standing here possible.
