High Fidelity is a great book, I feel like I've read it every year for the past 10+ years. It's one of those books where I first enjoyed all of the music references when I was younger and now that I'm older I felt like I fully understood Rob.
First it was like, "oh that's so cool that he is really into records, and goes to shows and owns a record shop." The past few years I've realized the commentary he has about balance in life and how a partner can bring that to your life. When you lose that, it can be very hard emotionally. I feel that I have grown much more empathetic to Rob because I've been there and know what he's going through.
I like it when books are like that.
