Marking corners of property and each family member peeing there, I read, was an ancient practice to keep out bad spirits and general stuff and to create a safe spot, in your British Isles.
When we moved to Tortolita, my son (very young) and I did such a ritual at each corner of the property from one of those pagan books. It gave him, and me I suppose, a better sense of home. We bonded as family and to our home zone. This was OUR safe place and of belonging.
