I was at the supermarket car-park when the policeman approached me and asked to breathalyse me. It was 6 am. "But I only had a half-glass of wine last night", I protested, before slumping over the wheel. (The bottom half of a small, handmade, Fair-Trade glass, to be absolutely accurate.)
He checked the machine - it was clear - before sighing, "Madam, can I suggest you get a bit more sleep?"
Then I woke up to the alarm-clock going off - it was 5.30 am and time to go to Asda! Could it possibly have been preying on my mind as I slept???
