Louise Erdrich said this quote

For much of my life I was not acquainted with what may seem the obscure derivation of the adjective 'sincere.' It is from two Latin words, sine, without, and cera, wax. What a rare thing it is to be treated without wax. My desire is always to conduct relationships based upon honest regard. As I sipped the last drops of beef tea I tried to enumerate moments stripped of pretense and all I could come up with was those efforts of mine, with brother-in-law, when he grasped my hand in desperate gratitude, unknowing, and allowed me to really see him. As I relived those moments of extremity, a strange thought met me unawares. Were I not to know him, or someone, some person, at this radical depth, I fear my time on earth would be hideous. I was surprised to think this. But it crossed my mind that to know others on a superficial level only is a desperate hell and life is worth living only if the veneer is stripped away, the polish, the wax, and we see the true grain of the other no matter how far less than perfect, even ugly, even savage at the heart.
