I'm totally baffled by my own daughter (middle grader). The most important things in life (seriously!) are clothes, those teeny-promis (Selina Gomez and friends), and whatever girl problem happened in school 'so and so said so and so and now so and so won't talk to so and so because so and so is soooo upset that so and so...'
And if you think this reads bad, you should hear it in real life context!
If anyone would use her real life thoughts and speech in a book, they'd either get lost by the second chapter---- or run down the street pulling thier hair out. (Yep, I've considered this at times
Hmmm... maybe it'd work in a cartoon, though.
