In the earliest hours, the baritone drone of Radio National would lead me to my mum’s dark room, lit only by the neon red display of her clock radio. ‘Mum? Are you awake?’ I’d yell-whisper at her exhausted sleeping form. ‘Mum? I can’t sleep,’ I’d persist. ‘Go back to your bed, lie down and try.’ she’d murmur patiently, digging deeper under the covers. ‘I already did that.’ No reply, no movement. ‘Ok mum,’ in my loudest whisper, ’I’ll try again. Goodnight.’ I’d creep back to my room, hitting every creaking floorboard along the way, lie down and instantly fall fast asleep.
