(Spoilers Published) Personal experiences that made you understand better the series?
For example, my mom was widowed when I was young, so every Catelyn chapter in ACOK onwards was like a stab in the chest.
Also, I'm an only child and read the series in 2013, way before meeting my wife. The Baratheon brothers were my favorites.
After meeting my wife, I could understand the scope of their tragedy. My wife had to basically raise her youngest sister. Just then I could grasp how betrayed Stannis must have felt when Renly sided with the Tyrells (and a rereading made me finally fully understand how much he misses his brothers).
Sorry if this comes across as too personal. I just find it curious how certain experiences can give you a different perspective on what happens in the books.
