“When you are in a relationship, you are aware that it might end. You might grow apart, find someone else, simply fall out of love. But a friendship isn't a zero-sum game, and as such, you assume that it will last forever, especially an old friendship. You take its permanence for grandted, whuch might be the very thing so dear about it.”

“I wonder why I miss her and Dex does not. Perhaps it is because I've known her so much longer. Or maybe it's the very nature of a friendship versus an intimate relationship. When you are in a relationship, you are aware that it might end. You grow apart, find someone else, simply fall out of love. But a friendship isn't a zero-sum game, and as such, you assume it will last forever, especially an old friendship. You take its permanence for granted, which might be the very thing so dear about it.”

“I think the important thing to remember is that all relationships benefit from a bit of breathing room. Especially friendships. It's only when you find yourself without the women who understand you that you realize there are very few women who will.”

“So how come people fall out of love, do you think?I don't know. It's true that people change. Or people don't change when you hoped they might. Or they find somebody else they like better. Or people just grow apart, they lose interest in each other's lives. Maybe they realise they made a mistake. There are lots of reasons.”

“And so a person can never promise to love someone forever because you never know what might come up, what terrible thing the person you love might do.”

“Parents don’t get that, though. They don’t understand about the fragility of teen friendships. They don’t understand how easy it is for things to break apart, how someone you thought would be by your side forever can just disappear, or turn on you, or decide she likes someone more than she likes you. Parents always talk about romantic relationships being so ephemeral and fleeting in high school. What they don’t get is that friendships can be the same way.”
