Why not pass that responsibility on next year, or in other years? Why not pass them on to her son's rather than sell them?
Imo they are selling them now before the Coronation because they were friends of Diana, there are many admirers of hers who will buy the letters and the couple want as much profit to go to the charities as possible.
They’ve obviously discussed it with their adult children and the children don’t want the responsibility. This couple, although I don’t know them, may well not want the responsibility in their own old age either.
From the article
The couple are selling the letters because 'owning the documents is a great responsibility' that they did not wish to pass on to their children.
Why, oh why, would the Daily Mail print such utter bilge? Better still, why do they continue to think anyone, either pro or anti Diana believers would believe that the onerous weight of the "Responsibility" of owning them was too great and forcing them to put them up for auction. Are we really expected to believe that the sale of a unique and intimately personal collection of letters is not first and foremost to ferment anger, hatred, pain and humiliation for the BRF and not an insignificant amount of money as the collection is broken up and the letters sold singly That amount could be even larger if someone bids on every single one in an effort to reassemble the collection.
This auction is designed to cause as much pain and suffering to the BRF and within this onerous problem, the feelings of Diana's sons William and Harry are worth nothing. Not their pain, not their anger, not their humiliation as they endure yet another action replay of the hardest time in their life, culminating as it did, with their mother's death. All churned up again in time for the Coronation, the sacrifice of their happiness in pursuit of money is abominable for the letters would fetch a tidy sum any time but at this time, timed as it is before the coronation, the Auction House will be releasing information from every single letter so those prospective buyers will know precisely what they are bidding for.
If they think that Diana's sons and family will thank them, they are as deluded as the Daily Mail is for stirring the pot. If the Kassem's think that Diana herself would thank them for the torment and pain that her sons have already suffered, and now it seems are doomed to repeat yet again, they are equally deluded, but I believe they are well aware of what they are doing and the knock-on effects, but the money and notoriety must be worth it.
