OEV - I am not denying it was good of them to send a letter, but you have tried to make her out to be a wonderful, caring and thoughtful woman, and that she sat down and personally wrote an individual letter to each and every family - she wasn't and she didn't - this was likely done as a PR exercise and image damage limitation - and regardless of those stories I do not believe she wrote those letters herself - perhaps she drafted one, but the rest will have been copies of this, i'd bet that any handwriting is different form letter to letter.
Notice also that the only handwritten bit was an add-on to a typed letter
I am not saying she didn't give a toss - she was human and you'd have to have a heart of stone not to care - especially if many believed you were largely to blame - but she was no queen of hearts
