If Nobody Speaks of Remarkable Things, by Jon McGregor

He does not speak of these things to people, there is nobody to speak them to here, nobody who knows. If he was asked he would say okay mostly, mostly I am okay, it is okay. But there are times when he feels too much, when if he could tell someone he would say I cannot possibly bear it anymore I want to tear the paper from the walls and fall to my knees and hammer upon the floor with my useless ruined fists.

He says my daughter, and all the love he has is wrapped up in the tone of his voice when he says those two words, he says my daughter you must always look with both of your eyes and listen with both of your ears. He says this is a very big world and there are many things you could miss if you are not careful. He says there are remarkable things all the time, right in front of us, but our eyes have like the clouds over the sun and our lives are paler and poorer if we do not see them for what they are.
He says, if nobody speaks of remarkable things, how can they be called remarkable?

Blood Red Road, by Moira Young

I never knew that missin somebody could hurt, I says. But it does. Deep inside. Like it's in my bones. We ain't never bin apart till now. Never. I dunno how to be without him. It's like... I ain't nuthin.

Clockwork Angel, by Cassandra Clare

“Sometimes,” Jem said, “our lives can change so fast that the change outpaces our minds and hearts. It’s those times, I think, when our lives have altered but we still long for the time before everything was altered—that is when we feel the greatest pain. I can tell you, though, from experience, you grow accustomed to it. You learn to live your new life, and you can’t imagine, or even really remember, how things were before.” 

A Series of Unfortunate Events: The Bad Beginning, by Lemony Snicket

The way sadness works is one of the strange riddles of the world. If you are stricken with a great sadness, you may feel as if you have been set aflame, not only because of the enormous pain, but also because your sadness may spread over your life, like smoke from an enormous fire. You might find it difficult to see anything but your own sadness, the way smoke can cover a landscape so that all anyone can see is black. You may find that if someone pours water all over you, you are damp and distracted, but not cured of your sadness, the way a fire department can douse a fire but never recover what has been burnt down.

The Graveyard Book, by Neil Gaiman

“You're alive, Bod. That means you have infinite potential. You can do anything, make anything, dream anything. If you can change the world, the world will change. Potential. Once you're dead, it's gone. Over. You've made what you've made, dreamed your dream, written your name. You may be buried here, you may even walk. But that potential is finished.” 

Unwind, by Neal Shusterman

"Blink twice if you can hear me."
Blink, blink.
"Good."
He locks his eyes on the nurse, whose eyes still smile. They always smile. Someone made her have eternally smiling eyes.
"I'm afraid you're going to have to stop blinking now."

Code Name Verity, by Elizabeth Wein 

All I have done is buy myself some time, the time to write this. I haven't really told anyone anything of use. I've only told a story.
But I have told the truth. Isn't that ironic? They sent me because I am so good at telling lies. But I have told the truth.
