“Why after all these years we've been together
must you behave as if we'd hardly ever spoken,
let alone met?
It seems that you're happy as long as I'm upset.
Oh why, oh why, oh why?
Is it that you don't love me? Oh why?
Have you just had enough of me?
Oh why do I always have cry myself to sleep
seven days a week?”

“"You're pining."
"Look who's talking. 'Oh, I love her. Oh, she's my sister. Oh why, why, why--'"”

“Oh God. Why, oh why, did I have to be the one to deliver this news? Why couldn’t I be locked away in my room or the library doing something enjoyable, like homework?”

“Alec shrugged "Look who's talking. 'Oh, I love her. Oh, she's my sister. Oh why, why, why--"
Jace threw a handful of dead leaves at Alec, making him splutter.
Isabelle was laughing. "You know he's right, Jace.”

“You could be happy, the minute you try.
Why won't you try? Oh won't you try?”

“I love you. Okay? Want it louder? I LOVE YOU. Spell it out, should I? I ell-oh-vee-ee why-oh-you. Want it backward? You love I.”

“Oh why rebuke you him that loves you so? / Lay breath so bitter on your bitter foe.”

“And so, what we've done all of these years is very simple, is use the little tool, which is ask three whys in a row. Because the first why you always have a good answer for. The second why, it starts getting difficult. By the third why, you don't really know why you're doing what you're doing.”

“You gave me the key of your heart, my love;
Then why did you make me knock?
Oh that was yesterday, saints above!
And last night—I changed the lock!”

“Oh, I'm starting to cry again. That's what happens when you think about life being fair. And I can't explain why it isn't… I don't think it's something anybody knows.”
