A friend of mine let me borrow Dune 1-3. I loved them and felt I would definitely re-read Dune. When the deluxe box set of 1-3 came out I bought it but it is just sitting on my shelf. I do plan on rereading them but probably not for awhile. Sometimes I also just like having the books I’ve read on my shelf as “trophies”.
My mum just told me earlier today that she’ll never get why I spend money on books that I’ve already read. For me, it’s a matter of self-expression, because my shelf says something about who I am - to guests, and to myself.
But it’s not even just that. They’re also souvenirs. If I’ve enjoyed my time in that world, with those characters, I don’t want to part with it. The physical book is a token of the time I spent and the adventures I had inside it.
