THE three-year-old son of a leading industrialist in town has, thanks to dad, been expanding his limited vocabulary. On taking delivery of his vintage Rolls-Royce, of which he is well pleased, dad picked up his son and proudly said: 'This is daddy's Rolls-Royce. Now say 'Rolls . . . Royce'.' As a member of that family, these are two words that will certainly stand the toddler in good stead in the future.
