“The First [Friend] is the alter ego, the man who first reveals to you that you are not alone in the world by turning out (beyond hope) to share all your most secret delights. There is nothing to be overcome in making him your friend; he and you join like raindrops on a window. But the Second Friend is the man who disagrees with you about everything. He is not so much the alter ego as the antiself. Of course he shares your interests; otherwise he would not become your friend at all. But he has approached them all at a different angle. He has read all the right books but has got the wrong thing out of every one. It is as if he spoke your language but mispronounced it. How can he be so nearly right and yet, invariably, just not right? He is as fascinating (and infuriating) as a woman. When you set out to correct his heresies, you will find that he forsooth to correct yours! And then you go at it, hammer and tongs, far into the night, night after night, or walking through fine country that neither gives a glance to, each learning the weight of the other's punches, and often more like mutually respectful enemies than friends. Actually (though it never seems so at the time) you modify one another's thought; out of this perpetual dogfight a community of mind and a deep affection emerge.”

“Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become and enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.”

“There are two types of people on planet Earth, Batman and Iron Man. Batman has a secret identity, right? So Bruce Wayne has to walk around every second of every day knowing that if somebody finds out his secret, his family is dead, his friends are dead, everyone he loves gets tortured to death by costumed supervillains. And he has to live with the weight of that secret every day. But not Tony Stark, he's open about who he is. He tells the world he's Iron Man, he doesn't give a shit. He doesn't have that shadow hanging over him, he doesn't have to spend energy building up those walls of lies around himself. You're one or the other - either you're one of those people who has to hide your real self because it would ruin you if it came out, because of your secret fetishes or addictions or crimes, or you're not one of those people. And the two groups aren't even living in the same universe.”

“Every child is affected thus the first time he is treated unfairly . All he thinks he has a right to when he comes to you to be yours is fairness. After you have been unfair to him he will love you again, but will never afterwards be the same boy. No one ever gets over the first unfairness; no one except Peter. He often met it, but he always forgot it. I suppose that was the real difference between him and all the rest.”

“He still went out nearly every night. I thought, is this what he's going to do when we have the baby? Have I made another terrible mistake with a man? You don't really know a man until you have a child with him. Then you see so much. Is he kind? Is he tolerant? Is he loving? Or is he immature and egotistical and selfish? When you have a child, it can go two ways with your husband: You love him even more, or you lose all respect for him. And if you lose respect, there's no way to get it back...”

“On his deathbed, my grandpa told me three things to remember for after he died. First he said, "You can't own a cat. Ever." Second he told me, "Friendly boys make friendly friends." Finally he said, "You were adopted, just like your father before you, and his father before him." "So," I said, "you were adopted?" "Of course not!" he replied. "Your father's not my son, just like he's not your father." And to this day I am still confused. I have no idea why I can't own a cat.”
