I enjoyed reading "I'm sorry you feel that way" more than I had expected. It is not light in terms of topics - family dynamics, unlovedness breeding unlovedness, mental health, deaths - but it's light in language, it reads easy, and if dysfunctional (AKA most) families interest you, I would recommend this one. I thought the ending was a little feel-good, but then the whole book is tragic in an everyday sense, and absurd at the same time. I found the characters a bit flat - each one had their defining characteristic, their "thing", and didn't really develop outside of that, except maybe Alice, and even then not majorly. However, the interplay of their personalities and relationships was rich and realistic, and Celia's complicated maternal love and loneliness were described thoughtfully.
