The following is from one of my favourite books of all time, This Boy's Life by Tobias Wolff:

"Then I got in the car. Dwight came up to the window, and said, 'Well, good luck.' He put out his hand. Helpless to stop myself, I shook it and wished him good luck too. But I didn't mean it any more than he did.

We hated each other. We hated each other so much that other feelings didn't get enough light. It disfigured me. When I think of Chinook, I have to search for the faces of my friends, their voices, the rooms where I was made welcome. But I can always see Dwight's face and hear his voice. I hear his voice in my own when I speak to my children in anger. They hear it too, and look at me in surprise. My youngest once said, 'Don't you love me anymore?'"

...and those are two of the best paragraphs ever written about anything.
