10 Poignant Quotes From Blue Sisters by Coco Mellors

1. On Sisterhood

“A sister is not a friend. Who can explain the urge to take a relationship as primal and complex as a sibling and reduce it to something as replaceable, as banal as a friend? […] Look at an umbilical cord—tough, sinuous, unlovely, yet essential—and compare it to a friendship bracelet of brightly woven thread. That is the difference between a sister and a friend.”

“You never have to explain yourself to sisters.”

“Being one of four sisters always felt like being part of something magic. […] Four chambers of a human heart.”

2. On Grief and Loss

“I miss her and I miss her and I miss her […] And part of me is glad [the missing] won’t end because it’s all I have to connect me to her now.”

“The problem with her pain was that it was invisible. Avery wished she could have given it crutches, some object that made it obvious to everyone around her, but she had learned now that most pain is private.”

“But what they don’t know is this: As long as you are alive, it is never too late to be found.”

3. On Love and Devotion

“Avery had previously thought love was built on large, visible gestures, but a marriage turned out to be the accrual of ordinary, almost inconsequential, acts of daily devotion.”

“It was easy to love someone in the beginnings and endings; it was all the time in between that was so hard.”

“I love you too. Without the too.”

4. On Survival and Healing

“I believe that everything happens. Period. […] The meaning is an afterthought, an anesthesia. Happens is the only word in that statement that’s empirical. The rest is whatever helps you sleep at night.”

“the best way to honor her sister would be to live life the way Nicky had wanted to, wide-awake and not numbing any part of it.”
