It meant that once I was back on familiar ground I still wasn't, exactly. Most of the run was on the same streets, but taking the loop counter-clockwise instead of clockwise made everything look surprisingly different. A few times I had to remind myself that things were familiar because it felt so strange.
I know there's a deep thought here about perspective and about how changing something really simple can feel really huge but I can't articulate that very clearly right now. I just know that I should make a point of running the other way around my loop every once in a while.
