The first thing I noticed was when the radio cleared its throat. I don’t sleep well and tend to leave the radio on all night, so when I wake up at five in the morning it’s there.

First I thought, That’s odd; then I thought, The presenter must have left the mic on, or not realised the piece has finished. Then a voice said, “Are you awake?”
