Hatred towards younger brother

When I was young, around after the black cat incident from the previous post,
My brother and I would often quarrel even now...
But sometimes, this memory could not be forgotten...
Last time, when I was around 4-7years old, my brother had a gruelling quarrel...
My brother started it since he was a really sore loser then, now onli a little...
We played the small monster car(hard to explain due to the thing being old)
The name of mine was Garuda Eagle(a machine fitted with a moving sword)
His was another...
When I won at that time(forgot how we played), he got angry and cried loudly...
Grandmother came out of the kitchen and yelled at me for no reason...
When I was about to go to the kitchen to take something to drink, it happened...
My bro took both machines and threw them at me!
I was lucky enough to evade his which was quite dangerous...
But mine hit me in the forehead...
The same place where I hit the sharp door edge in the previous post...
Blood came flowing from it...
I got angry without realising what happened to me and whacked him till he cried louder!
Then my parents came home and scolded me for making him cried...
By then the blood had stopped comming out...
After that incident, I really hated my brother!
Sometimes in the day, something in me will become angry and feel like whacking him to death!
Think my patience had depleted after that...
I took up the CCA Art Club which was like the school's deco comittee...
Now, I really can't stand him so I always listen to songs very loudly to ignore him!
I even try to go out with friends to stay away from him!
I think he just have to count himself lucky I did those things...
