Diana was a distressed soul, something that was so obvious to a casual observer like myself standing in the street. My severest criticism of the RF and Diana's family had been that they 'did nothing' to reign in this young woman. It was a situation that caused me to experience increasing anger as the years wore on - but I now know I was mistaken. Given what I have learned over the past half year, one fact is glaring - that the RF and Diana's family absolutely were aware of Diana's problems, tried to help, tried to support, tried - but were undone by Diana's lies and wileyness.
When one has a fuller understanding of just how out-of-focus with reality Diana was, the Queen making herself available at any time to Diana is a red flag - and is a confirmation that the RF did indeed understand the situation with Diana. The Queen's availability would seem to be part of trying to work with what was a seriously problematic young woman. No other explanation fits IMO for such an unusual divergence from the norm for the Queen.
