Due to general incompetence on my part I bought a flight home from Santander instead of Santiago, and so had to back track to near where I started. I had a few days in hand, and so bused to one of my favourite parts and started walking again towards Santander. I was worried that my credencial would be questioned, given that I had the stamp from Santiago in it, but the reality was no one batted an eyelid, and when I did explain why I was walking again, everyone was just amused at my error. This re walking let me muse on the idea of walking back.
I was told while walking the camino, that tradition said you could tell those who had reached Santiago and were now walking home, by the light in their eyes.
I always thought "By the light in their eyes" would be a good title for a camino book. My favourite walkers with the light in their eyes were a British couple I met who had started walking from their home in France, to Santiago via the Frances and were now walking home via the Norte. He was 82 years old, but said he wasn't allowed to say his wifes age, however he gave a conspiratorial wink and said quietly "between us we have 150 years". I hope you have a great time on the way home.
