It is realising that we are each of us alone
"It is realising that we are each of us alone, that no one is ever entirely right for us because we are all broken, and that we can only open our broken aloneness to that of another. A good relationship, like a good parent or a good death, need only be ‘good enough’, consisting of two people navigating each other’s inadequacies with kindness and sympathy. "
Derren Brown, "Happy"
I love the concepts expressed here, especially the idea of opening our broken aloneness to that of another.
Having been in a relationship with the same person for twenty years, the concept of navigating each other's inadequacies with kindness and sympathy is definitely something that deepens over time.
