i think that as an only child i can only give you a tiny bit of the impact this book had on me, from my perspective, which is very far away from the topic this story is about.
i always loved being an only child, since i was little, my life was not pretty at all, with a very messy separation from my parents and living most of my life with one of them, what i always thought was: "well at least there's only one they have to worry about", at that time i didn't think that maybe if i wasn't alone it could be easier to take, all the fights and problems, two is always better than one right?
but now that i'm an adult, and i see what the future will bring, i really wish i had a sibling, someone to walk this life with. being an only child is both a blessing and a burden sometimes, the good part is that i don't have to deal with nobody else's problems, or bad attitude (there's a lot of bad relationships between siblings in my family), but the ugly part is that i'll have to deal with everything alone, and yes i have friends that are like family now but there's always that little thing that's missing, the bond that only blood can give you, even when sometimes i tell myself that's not important when it comes to how much you love someone, see? it's a weird feeling this 'only child' mindset.
this book showed me how beautiful and messy a sister bond can be. it show me that no matter what you say or do, at the end of the day they're always there, picking you up, walking with you, this is the kind of sibling relationship that i hope everyone has, the way it should be. i was so emotional since the very beginning, it became one of my favorite books now, and i hope it becomes one of yours too.
