Pre-school teachers what are u guys doing!

Just recently, my little brother was beaten up(intentionally or unintentionally i don’t know) by another pre-schooler. He was beaten on the nose area.The impact caused him to bleed in the nose. The teacher also don’t know what the hell happened to my brother when i questioned her on monday. I was like WTH!!! My brother told me that he was beatened on the nose by some indian kid but the teacher do not know what happened! Wake up la ! CB how can you don’t know the things that happened in class?

To solve the problem…………i tell my brother to whack anybody that whacked him(self defence LOL)
