That’s what cliff notes are for. Explaining the background and context so you can better understand what you’re reading in, say, Hamlet.
Not just simplifying it and removing potentially relevant material.
For example in the example material:
They weren’t just younger. They were more vulnerable. That conveys a lot of meaning. Even the word “more” implies a current vulnerability.
Advice isn’t just something told or conveyed. It’s something given for the benefit of the recipient. I told my child to get milk isn’t the same as giving them advice about drinking milk that’s set out.
Turning over in my mind ever since -> I still think about is the closest it got to being right. Even then, though, turning over conveys a more meditation/consideration than just thinking about something.
