Anger Management

Okay so I have a problem with my temper but its really not my fault because I live with such annnoying and infuriating people I really could hurt them sometimes :[ I swear
The one in my wrath path atm is my dear eldest sister Katey. Such is her nature that every slight ailment or flush in her cheeks must be the plague. She is so melodramatic I just want to kick her several times - hard! But no ones sees this as a problem or they take the 'she's 22 there's nothing we can do' line of argument. But honestly she still lives at home and eats our food and expects mum to do her washing so why shouldn't she abide by the household rules or at least by social norms. This has been annoying me for quite a long times - we quite often playfully dispute and she quite often pokes me. I take it quite amicably and poke her back. She consequently rushes off in agony to protest to our mother (she also happens to be the biggest snitch of all times - no you never grow out of it) Now I'm no hulk - I can't be doing that much more damage than her. The difference is that I can take it, if someone pokes me perhaps it stings minorly for a few seconds - at most a minute. That sort of pain is like a bee sting compared to a bullet wound. How can she get away with crying murder at every last poke when I don't even complain? That's just the start.
She likes my other sister better than me. That I have known for quite a while as well. She sometimes like to bitch about how she's mums favourite (not really true) but on the whole she prefers Harriet to me. She talks to her more, goes out with her more etc. I know we live together so we do happen to go out more than she does with Harriet but trust me thats more because she has an incability to go anywhere on her own than pure choice. As soon as Harriet came home from University it was goodbye to our time. When anything big happens - she tells Harriet. She had a story to tell and we had to wait for Harriet before she would tell it. But we didn't have to wait for me. Oh know, as soon as I left for a shower and Harriet appeared it was oh well I can tell it now. And when later on I asked her about it all she could say was I'm so tired of telling this story I can't be bothered. Oh well thanks for that and how many times had she recalled this story that meant she couldn't stand even the thought of the words? Only about once.
So now she's seeing this guy and she's way too sick to go out with him so he has to come here. Joy. And een better she comes into my room attacks me and then announces that I am not allowed in the playroom because he is coming over. Fair enough, I thought, its only fair the visitor gets to spend the time in the room. But hang on a minute I didn't say asked I said told. She is no more owner of this house than me and she tells me that I can't have the room? Now I will have to spend the night being subjected to Foyle's f***ing War.
And then there's her mothering complex. Just because she's four years older than me she thinks she can order me round this house. She'll just tell me to do anything and then reproach me for not doing it. I'm like funny you don't look like my mother? And then she''l turn round and say respect your elders?! Okay a well respected phrase but seriously? The Bible only says honour they parents but just those people older than you? How so? I may only be 18 but does that mean I should show respect to all those people older than me? Even those people who sit around scamming off benefits only to shout slurs about f***ing foreigners? Do those sorts of people even deserve respect? In my book there are some people who deserve respect; parents teachers, old people (you can't screw with old people its cruel), priests etc but notice all those who are older than me... DO you think people younger than me respect me? No. So all those who don't automatically demand respect well they have to earn it. I respect some people because of the actions I have seen them do. Because of the things they have done for other people, for me and for themselves. But the fact that someone is born 4 years before me does not earn them my respect. So when someone argues with me and then finishes with 'respect your elders' well they succeed only in lighting a touchpaper under my temper. It's like the person who ends an argument with 'because I said so.' It is argumentively weak and nothing makes me angrier then a person who thinks themselves above people in such a manner.
Apart from perhaps when someone interrupts me to tell me I'm not listening. But that is for another rant.
