Dear Louie, You've been asking and asking about what middle school is like, but I just thought they were annoying-younger-sister questions. Even though I am almost done with my first year, I can still remember when I thought middle school was a mystery, so I'll try to give you a leg up. I know middle school is a lot to figure out. But since I still haven't worked it all out yet, I'm happy to help as much as I can. That's what big sisters are for. Love, Gus. Discover the ins and outs of middle school in this guide from an older sister to her younger sister. From tackling a new building to meeting new people like the assistant principal, the class pet, the Huggers, the renegade, the tomato kid, your old best friend's new best friend, this is a must-read for everyone starting middle school.
