This would be unsettling if it were one of my relatives. Of course, with everything else they have to deal with, perhaps the residents are all saying, "Eh, just put her back in the ground whenever."
We had something like that happen around where the ocean was washing out an old slave cemetary and the coffins were floating out to sea. The markers were long gone so no one knew exactly where people were buried.
Doode, you know on MXC how they try to run across the rock things to get across the water, and some give way???? We could totally do that with those coffins.....
