Sisters suck.

I try to like my sister, and she is likeable sometimes. Some of our friend came over today, we played games and went swimming all that stuff. I think she has a problem with other peoples personalities, like mind for example. She doesn't understand that I know how to hold my tounge around people, unlike her, I know how to be courtious, and polite. She just says stuff, inapproprate stuff at the worst moments. It's like she gives no thought to her friends, she openly mocks me and says stuff about me that I would rather she not said in front of our friends. I think they know what she is doing, but they wont say anything about. She gets mad a me for being civil and acting all goody-goody around them, maybe so, but I act appropirately for the occasion. She doesn't care what anyone thinks of her, but when they voice their opinion,she gets mad about why they even care in the first place, she claims that she doesn't care one moment, and them blows up in your face the next about something she claims she doesn't care about. Face it, she is a walking contradiction. I hope that one day she will come to terms with her loud personality, because apparently because I'm her sister, I just don't count.
