Ask HN: Article about Stanford Professor's Friday sayings

Within the past month there was a comment where the author talked about a Stanford professor who would talk about a lesson or musing on Fridays. They linked to an article the Professor wrote about relationships, and scars and how scars are never as strong as the pre-scar state. It was very powerful and I want to share it with family but I cannot for the life of me find the link to it.

Thank you.
