Disturbance

So I apparently need anger management now. Why?... 2 incidents happened these few months...
both have to do with knowing how to deal with an insane sibling who finds pleasure in disturbing me. Contain my anger and manage it?... I'd rather manage him to be honest.
analyze this:

whenever you wake up in the morning and that sibling's around... you may be reading, watching a movie or studying (that's usually rare but during exams it's quite often)... but every time you do these things this sibling of yours (whenever he's around) would barge into the room and either walk around your desk to see what you're doing (which I usually never give him the chance)... or play with your things (whatever he gets his eyes on).. or simply stand there in front of you talking crap while you're not in the mood and trying to concentrate on something else... and if you don't give him a face or cuss him out.. he finds anything he could to blackmail you (in the hopes of teaching you a lesson to start respecting his sorry ass).
Now imagine telling him to leave you alone and he doesn't listen... then imagine moving up to the 2nd stage of telling him to butt off and he still doesn't listen. Take your imagination to the 3rd stage and think of this happening to you every day for a whole week...
I'm sorry what?... 6 years old?... no no... he's 23 years old... you heard me right...

what were the incidents that made my anger get out of control? once I gave him a zillion warnings to leave me alone and because I was not friendly to him, he cut off the internet from me using the excuse that I was not studying (which was never his business). I had to get him back somehow... and no one was around at home to show him his limits. The only thing I saw were a pair of shoes. His most expensive ones I guess. yes yes... I destroyed them... more like cut them. You think that's extreme? It gave me the results I wanted.
my dad wasn't happy about that but my bro was told to stop disturbing me ever since (1 incident)... the 2nd incident was yesterday... when I again gave him warnings and after a long time of stubbornness from his side I took anything I saw in the table and got ready to throw it at him. He knew I would do it so he walked away saying that he'd tell my dad about this.

I wonder if any of the readers have a brother like that... those who don't... I can only confess you're much better off without it.
