Find an example of foreshadowing on page 83. What does it mean?

August is the Sun. Me and Mom and Dad are planets orbiting the Sun. The rest of our family and friends are asteroids and comets floating around the planets orbiting the Sun. The only celestial body that doesn't orbit August the Sun is Daisy the dog, and that's only because to her little doggy eyes, August's face doesn't look very different from any other human's face. To Daisy, all our faces look alike, as flat and pale as the moon.
I'm used to the way this universe works. I've never minded it because it's all I've ever known. I've always understood that August is special and has special needs. If I was playing too loudly and he was trying to take a nap, I knew I would have to play something else because he needed his rest after some procedure or other had left him weak and in pain. If I wanted Mom and Dad to watch me play soccer, I knew that nine out of ten times they'd miss it because they were busy shuttling August to speech therapy or physical therapy or a new specialist or a surgery.
Mom and Dad would always say I was the most understanding little girl in the world. I don't know about that, just that I understood there was no point in complaining. I've seen August after his surgeries: his little face bandaged up and swollen, his tiny body full of IVs and tubes to keep him alive. After you've seen someone else going through that, it feels kind of crazy to complain over not getting the toy you had asked for, or your mom missing a school play. I knew this even when I was six years old. No one ever told it to me. I just knew it.
So I've gotten used to not complaining, and I've gotten used to not bothering Mom and Dad with little stuff. I've gotten used to figuring things out on my own: how to put toys together, how to organize my life so I don't miss friends' birthday parties, how to stay on top of my schoolwork so I never fall behind in class. I've never asked for help with my homework. Never needed reminding to finish a project or study for a test. If I was having trouble with a subject in school, I'd go home and study it until I figured it out on my own. I taught myself how to convert fractions into decimal points by going online. I've done every school project pretty much by myself. When Mom or Dad ask me how things are going in school, I've always said "good"—even when it hasn't always been so good. My worst day, worst fall, worst headache, worst bruise, worst cramp, worst mean thing anyone could say has always been nothing compared to what August has gone through. This isn't me being noble, by the way: it's just the way I know it is.
And this is the way it's always been for me, for the little universe of us. But this year there seems to be a shift in the cosmos. The galaxy is changing. Planets are falling out of alignment.
