“Sometimes silence was easiest, when the only word left was good-bye.”

“I was trying to feel some kind of good-bye. I mean I’ve left schools and places I didn’t even know I was leaving them. I hate that. I don’t care if it’s a sad good-bye or a bad good-bye, but when I leave a place I like to know I’m leaving it. If you don’t you feel even worse.”

“Yeah you can have a word," said Harry savagely. "Good-bye.”

“You [meaning mothers] said good-bye a little every day -- from the minute they left your body until they left your home.”

“Sometimes words are more powerful than guns. And sometimes silence is more powerful than words. It is the things that are not said that are important.”

“i do not say 'good-bye.' i believe that's one of the bullshittiest words ever invented. it's not like you're given the choice to say 'bad-bye' or 'awful-bye' or 'couldn't-care-less-about-you-bye.' every time you leave, it's supposed to be a good one. well, i don't believe in that. i believe against that.”
