Wow, I absolutely love this! It's humorous, and Gilda almost reminds me of how I was just a few years ago (not daydreaming about dating my teachers, though. My teachers were OLLDDD). And I love the way you compare the cliques in schools with ice cream flavors. I actually never thought of it that way before.
Though, a word of advice would be to watch the way you phrase certain things. Sometimes, particularly in chapter 1, some sentences seemed a little awkward. Other than that, make sure you proofread. A few typos here and there. Great work!
