A radical change of mind

[sawyl]

I was rather struck by this comment from a cemetary operations manager, quoted in today's Guardian Weekend:

Sometimes we do exhumations. The grave owner must obtain an exhumation licence before we can do this. There have been cases of people who have moved away from the area and wanted to take their loved ones with them, or wanted to transport them back to their roots abroad. Some people have an aversion to burial and decide they would rather have a cremation after all.

I wonder how they find out whether the person has developed an aversion to burial or not. A ouija board, perhaps?
