I'm linking to this story because I'm intrigued by items people leave at gravesites. What is the point in leaving something? When someone leaves flowers at the tombstone of a loved one, what are they hoping to accomplish? Obviously, the dead person is incapable of watching flowers transform from liveliness to decay. Only those who visit the graveyard will see the flowers, and the vast majority will not give them a second glance, no matter how elaborate and lovely they are.
When a son leaves a note - to tell his deceased father about what has transpired in the world since he expired, or whatever - no one would seriously suggest that the corpse could rise to read it. The son leaves the note for others to see. Would the son have left the note if the father was buried in some obscure place, instead of one of the most visited graveyards in the world?
