Anyone who has lost a child of any age, never 'moves on'.
What they do is learn to live alongside it. The grief does not get any less as the years pass. Infact it becomes worse at times because it accentuates how long it is since you last saw your child.
Time is not a healer and peace is forever illusive.
What the people of Aberfan must have wanted was to be left alone with their memories and anniversaries.
It is good people remember the loss of so many lives but press coverage and people converging in thier town year after years must have been pure agony.
