Most people, on waking up, accelerate through a quick panicky pre-consciousness check-up: who am I, where am I, who is he/she, good god, why am I cuddling a policeman's helmet, what happened last night?And this is because people are riddled by Doubt. It is the engine that drives them through their lives. It is the elastic band in the little model aeroplane of their soul, and they spend their time winding it up until it knots. Early morning is the worst time -there's that little moment of panic in case You have drifted away in the night and something else has moved in. This never happened to Granny Weatherwax. She went straight from asleep to instant operation on all six cylinders. She never needed to find herself because she always knew who was doing the looking.
