So we were walking down the road next to the local church today and a man was pacing across the stretch of the graveyard, but then I noticed a pair of shoes on the ground & then that he was barefoot.. 
Is this a thing?
My friend said maybe he's pacing the distance between graves, but why would you take your shoes off?
Any ideas? Is this something priests do?
The graveyard doesn't have any recent burials, it's a very old one, with very spread out gravestones.. if that's at all relevant to the situation.
