Harry Potter and the Cursed Child by J.K. Rowling

“Harry, there is never a perfect answer in this messy, emotional world. Perfection is beyond the reach of humankind, beyond the reach of magic. In every shining moment of happiness is that drop of poison: the knowledge that pain will come again. Be honest to those you love, show your pain. To suffer is as human as to breathe.”

“Those we love never truly leave us, Harry. There are things that death cannot touch.”

“We cannot protect the young from harm. Pain must and will come.”

“The truth is a beautiful and terrible thing, and should therefore be treated with great caution.”

“The world changes and we change with it. I am better off in this world. But the world is not better. And I don’t want that.” 

“If I had to choose a companion to be at the return of eternal darkness with, I’d choose you.”

“Love blinds. We have both tried to give our sons, not what they needed, but what we needed. We’ve been so busy trying to rewrite our own pasts, we’ve blighted their present.” 

“It is exceptionally lonely, being Draco Malfoy. I will always be suspected. There is no escaping the past.” 

“One person. All it takes is one person.”
