Do you ever analyze a book you're reading for fun?

Yeah, this sounds a bit like what I'm doing now. I'm looking at what phrases the author keeps repeating, thinking about who's perspective is shown in the chapter titles (some titles are in first person, but the story is written in third person), trying to figure out what the author is saying without directly spelling it out. But what do you mean by "not just silly entertainment"?

"Just silly entertainment" could for instance be a short story that I read in a magazine when I am at the hairdresser. But if I have just read a really heavy, interesting and challenging piece of literature then my little brain sometimes is overtaxed and to give it a chance to relax I often choose to read something very simple and trivial.
One thing that I would like to say to you is that when you read and especially when you analyse you should be aware that the meaning and value of a word can differ very much depending on when the text is written. You are so young that I guess that you have not yet experienced this phenomenon but as an example I can mention that when I was young in the hippie-time in the late sixties and early seventies the word established was one of the worst insults young people could use when criticising people over the age of 30.
Good luck with the reading & analysing.

That's a good way to look at it too

@hiddenkitty: lol thnx.😁😁

That is sad but I know how it is; when we get older we find out that we do not need to think as much as before but can in many things rely on experience.
