What did Snape say outside the church in Harry Potter?

"It's not fair ... we shouldn't have come ... but here we are ... it's like an adventure story we've heard ... praising great behavior, full of darkness and danger ... sometimes you don't want to know the ending, because how can there be a happy ending? ..... So many terrible things have happened, how can the world go back to the past? But in the end, the terrible shadow ... will eventually disappear, even the darkness will disappear, a brand-new day will come, and the sun will be brighter ... This is unforgettable. A touching story of great significance. Although you are too young to understand why, I think I understand ... I understand now that the protagonists in these stories have many opportunities to give up halfway, but they don't. They decided to move on ... because they had a belief ... (Frodo: What belief do we have, Sam? ) .............. There must be goodness in this world .........................................................................................................................................................

Just like a great story, Mr. Frodo. What really matters. Full of darkness and danger. Sometimes you don't want to know the ending. Because how can the ending be happy? With so many bad things happening, how can the world go back to the past? But in the end, it's just a passing thing, this shadow. Even the darkness will pass. A new day will come. When the sun shines, it will be brighter. These stories are always with you. What this means. Even if you are too young to understand why. But I think, Mr. Frodo, I understand. I know now. The people in those stories had many opportunities to look back, but they didn't. Because they insist. Mr. Frodo, there is still a bright side in this world. It is worth fighting for.
