Glancing in my rear-view mirror whilst driving to my counsellor training class I saw only busy motorway traffic behind me, yet oddly memories arose of when — just occasionally on winding country lanes — my rear-view mirror had revealed such entrancing scenery as to be dangerous, requiring my every ounce of will for return to safe-driving focus. "But that's impossible on this ugly flat motorway" I thought, then decided to overtake a lorry. So I looked in my wing-mirror — it was filled with a glorious rainbow spectrum — and my every ounce of will for return to safe-driving focus was instantly vital.
