one person who makes me angry

in the world, theres one person who can make me turn from a happy chappy to a shouting bastard.

ive generally got good anger management. I dont really have problems with anger anywhere nowadays, except to this one person who for some reason makes my blood boil. its a very inconvenient position too. all my friends, relations, and the like, can do things to anger me but i dont care, i can get over it, work it out, talk it through. its usually other people getting angry and then getting more angry that im not angry!

but this person can make me instantly start shouting at their face, wanting them out of my space. its not that i want to actively hurt them, i just want them to go away. i often resort to physically trying to push them out of my room because theyre pissing me off by just being around. i just want them to shuttup because it seems theyre so DUMB sometimes, and never take in waht I have to say anyway. this might be the reason it happens. i can be happily doin whatever, then they will come into the room, ask me something theyve asked me a million times, patronise me, or simply want to stay around and talk about something that i will not talk about something.

when i try to get them to leave they make out like its a violation.. but ive tried so many things and the only way i can get them to leave me alone (ive tried a lot of things such as remaining calm, talking things through but that makes them seem to want to stay around longer) is by raising my voice to a shout (and then once again being made out like this is a violation which makes me even more angry - 'dont shout at me!' 'if i dont shout you dont LISTEN!' 'dont raise your voice!' ' OMG PISS OFF'), physically trying to move the person out the door so i can close it and lock it and get on with my business (work, rest or play, whatever it is), or by telling them what i really think about them, which makes them sad and go mope, which in turn makes me feel guilty when they didnt have to come talk to me at all and i told them to leave the subject alone so much AAARRRGGHHJHH.

ive never hit them, and i never would, but they seem to treat me trying to shift them out of my room as almost the same sort of thing.

they can make me angry by moving things, by tidying my stuff, by just commenting on the state of my room.

i wish this didnt have to happen. we have a great relationship whenever the person doesnt try to get involved with my actual life.
of course thats not really an option for the moment

it just makes it worse and worse as they get older and begin to lose the judgement and awareness they used to have, and as i get older and more impatient with their lack of understanding to my increasingly individual life.

and it sucks that i can get over anger with everyone and everything except them because ive had my whole life trying ways around it and the only thing that works is ignoring the person which makes my situation worse.

i think you can all guess who this person is
