I realized that the aspects of a person that remain unknown are what truly define their humanity. This thought came to me while returning from the rock field, highlighting the mystery and depth of human nature. The idea made me feel a mix of sadness and comfort, as if acknowledging that not knowing everything about someone is a natural and accepted part of being human.

"I had a thought, on the way home from the rock field, that the things we don't know about a person are the things that make them human, and it made me feel sad to think that, but sad in that reassuring way that some sadness has, a sadness that says welcome home in twelve different languages." This quote reflects a deep understanding that mystery and ignorance about others are inherent to human experience and that there is a strange warmth in accepting this unknowability.
