The impression is fresh for a while. What is the first thing you do?
Do you discuss it? Do you write some kind of review for yourself? Do you explore professional reviews/analyses instead to compare the perspectives? Do you give yourself some time to form an opinion? Do you do something else?
Oh god this is depressing. I used to immediately go on reddit to see if anyone else had read it and read what they thought 🤣
Apart from that I wear the ear off my partner about the writing and the themes and the cultural context and how reading it in the 21st century changes the text. I rarely write down what I thought of a book, but that actually sounds like quite a nice thing to do.
