My Brother's Problem!!!

When my brother was very young,he was very cute.

But when he entrance into a kindergarden,he has changed.
He sometimes he defy one's elder,like me!!

When I told him to eat his lunch all,he said
"Why?I don't want to eat them all!!"

But I cannot help doing to told him to eat his lunch all because

he made his lunch very dirty..

So I said "Hey,if you don't it eat all,I will tell..." "Aaaaa~~~~Ican't hear you!!"

I was so angry but I had to ignore him because if I hit him he will tell to my mother.

So I ignore him. But yesterday!!I couldn't ignore him...

When he was play with him,

he bothered(?)my mother,so I said"Don't do that!"

and hit him.But he said"Why did you hit me!!"

and he hit me very~stong.So I cried,but I had to hold my mind because I'm the elder sister..kkk

But I want to correct my brother's behavior.

I think he learned from other boys that has bad behavior.

It is very had that my brother learned bad behavior from other boys.

What should I do???
