I loved Normal People. This is a book I didn't expect to enjoy at all (I'm not a fan of straight people romance), but the characters and situations were so well fleshed-out, it made me fall in love. :)
My one big learning from this book was that you've got to face your demons first. You cannot carry the heaviness in your heart along forever and expect to be happy. Addressing your emotions and the trauma in your past is important.
I love your take on it and how you related it with the unpredictability of life. :)
