“Then there you are, then. The day Howl forgets to do that will be the day I believe he's really in love, and not before."
Michael to Sophie about wether or not Howl is really in love with Lettie. pg, 170”

“By now it was clear that Howl was in a mood to produce green slime any second. Sophie hurriedly put her sewing away. "I'll make some hot buttered toast," she said. "Is that all you can do in the face of tragedy??" Howl asked. "Make toast!”

“The next minute or so was spent howling on the ceiling. Imp No.1 joined in, but he wasn't really feeling it. It shouldn't be "Who do we hate?", he thought, it really should be "whom", but this probably wasn't a good time to bring that up.”

“And I can't go on this way,
With it stronger every day,
But being too shy to say
That I really love you.”

“"What you do is find your centre - can you do that?"
"My navel, you mean?" I said.
"No, no!" he howled. "You're not a woman! Or are you?"”

“Tell me of this Wizard Howl of yours."
Sophie's teeth chattered, but she said proudly, "He's the best wizard in Ingary or anywhere else. If he'd only had time, he would have defeated that djinn. And he's sly and selfish and vain as a peacock and cowardly and you can't pin him down to anything."
"Indeed?" asked Abdullah. "Strange that you should speak so proudly such a list of vices, most loving of ladies."
"What do you mean — vices?”

“Why were the good days always so short? Moment to moment, day by day—each so full, and oh so lovely—and then gone forever, gone before there was a chance to absorb them properly, to really live them.”

“Do you know what I really need?
I need love love love love love, yeah!”

“It's always hard to remember love - years pass and you say to yourself, Was I really in love, or was I just kidding myself? Was I really in love, or was I just pretending he was the man of my dreams? Was I really in love, or was I just desperate?”

“The only love that I really believe in is a mother’s love for her children.”
