The time I break the rule

On last Tuesday, at my first class, is LA, I was bring drink to the classroom, I don't know what to do so, I try to hide the bottle away. Then the next day, it was Wednesday, on the afternoon at the school, before the club start, I went to the canteen and buy some snack, went I went to class, I remember that there are no foods or drink in class, but I don't care, so went I came to class with the snack, the teacher is told me to not to bring food to the classroom any more. So, I learn a lesson, never bring food to class, the reason is the class may dirty, because went eat snack, maybe the piece will fall on the ground and bring ant to class, that is the time I break the class rule and I will never break it again
