It isn’t ashes, it clearly says he is buried in the garden.
It wouldn’t bother me especially. Graves in graveyards are much deeper than I would ever be digging in the garden.
Over the millennia of human life we’re probably all pretty close to some deeply buried human remains.
Terrible photos. My estate agents removed all sorts of stuff from different rooms before photographing them. No excuses for the black bags etc in shot.
Plus the family will have to remove all the stuff, so why not do it before the photos?
That’s a sad thing: clearly they don’t really give a shit
