"フロドは言った「私の時代にこんなことが起こらなければよかったのに」とガンダルフは言った「私もそうだし同じ時代を生きるすべての人もそう思っているしかしそれを決めるのは我々ではない我々が決めなければならないのは与えられた時間をどう使うかだ」"

Simplified Meaning:

Sometimes, things happen in life that we can't control or change, and they can be tough to deal with. Imagine if there's a big storm that destroys many houses in your town. You might wish the storm never happened, just like Frodo wishes bad events didn't happen during his life. Gandalf understands this feeling and says that everyone feels the same way when they face difficult times. However, he points out that we don't get to choose when such events happen. What we can control is our response to these events and how we use the time and resources we have. For example, after the storm, instead of dwelling on the disaster, people can come together to rebuild homes, support each other, and strengthen their community. This quote teaches us to focus on what we can do right now to make the best out of any situation, rather than wishing things were different.
