Exmoor not Heathrow

Set out for Heathrow to meet middle son for a few hours on his way through from South Africa (holiday) to Canada (home) when we had an altercation with another vehicle on a narrow Devon lane. Big bang to the driver's side wing mirror. Too dangerous to drive on motorways so disappointedly I resorted to tea and toast in South Molton and a scenic drive home.avoiding the diversion that had been the cause of the prang.
