Replacing paving stones

Walking down the sidewalk of a street in my childhood town, I wondered how it was possible that time was not experienced at this place, while having memories about being here before. Contemplating on the mystery and being present, there seemed to be no gap in time, time didn’t even exist.

To find clearance to the phenomenon, I replaced 10 paving stones for new ones. Driving around for two weeks with the old stones in the back of my car delivered no answer. Nothing happened.
By replacing the new stones for the old again, I made the whole operation undone.
