Hi, I came to spend my vacation with my parents and sister, she is 20, I am 25, she is driving me crazy, the way she acts and talks with/to me hurts me and she doesn't even know it, I have talked to mom and dad in a logical way and their response was very passive, they said that she doesn't show respect to them, how should I expect her to show respect to me, I am a very peaceful person, I am not used to fights, we didn't really fight, because I am not like that, had it been someone else (like my brother, who always fights with her)..I don't mean physical fight ofcourse, yesterday I tried to explain to her that the way she talks to other is impolite and she said that that is the way she is and if I don't like it I should not talk to her, so I am not talking to her, but what bugs me now is that my parents are taking all these issues lightly and they want us to be friends again..I have not been treated like this by my brother or other sister who are older than her...plus I am a very sensitive person and she knows it, I have been having a stomach ache ever since, it is like all goes to my intestines...I am very upset and hurt and I really don't think that I want to talk to her even if she came and opologized, infact she said to me that she is sorry if she did anything wrong but she hasn't...which even made me more nervous..i swear to God that I don't think I want to look in her face after what she has said and done...she is very selfish, only does things to herself, she does not acknowledge anyone in the house, she uses our stuff but won't let no one use hers, I don't even know if she is aware of how much pain she has casued me...please advice, how can you let these things go and not take them to our intestines..
