Our school is small, we only have about 100 students. And she didn't run away in embarrassment, my belief is she absolutely does not care about what others think of her.
The toy was a noisemaker. While she had the right to demand that I stop using it, she had no right whatsoever to steal it.
Aside from that, today was quite fun. I solved a "Tough"-difficulty sudoku, and decided to have some fun at my teacher's expense (The boring teacher that got us to the parliament on that stupid trip). So while the teacher was talking, I slammed my desk and started shouting "I AM A GENIUS COMPARED TO ALL YOU IDIOTS! I SOLVED A SUDOKU YOU WOULDN'T DARE TRY IN YOUR DREAMS! I DO NOT BELONG IN THIS PLACE, I SHOULD BE WORKING ON A PHD RIGHT NOW!". Even though that's at least partially true, I did it in a ridiculous manner just to disturb the lesson. It took the teacher ten whole minutes to get the students' attention back to the lesson. It was hilarious.
