I'm angry these days about my english class, I started it in february, it was always okay, but, this month I got a new class, the teacher is excelent as always, but my classmates are most children and it trouble me a lot, most of them don't want to learn anything and they delay our class with rebellious actions and their laziness, I'm not really sure if I want to stay in this class, perhaps I'll change it soon !
