One of the all time greats, and I'm sure a huge inspiration to "Only Fools and Horses." Harold was convinced he could have made it anywhere in life, but was held back by his possessive and selfish Father Albert. Yet he considered it his duty to look after his Father, who often succeeded in what Harold tried to accomplish! His impression of his domestic liabilities tended to shelter Harold from any of his own inadequecies, and the character drew comfort from his imagination of what might have been, if not for his Father. Harolds late Mother was a central character, cleverly etched, though we never saw her, relying only on the characters impressions of her memory.
