I can't deal with my sister's vendictive behaviour anymore. She is supposed to be 18 but she is sneaky and always trying to wind me up.
She will pull faces when people are not looking and then deny it when I bring it up in front of people. I will tell her things and then she will go and carry the story to someone else even when I explicitly ask her not to. She also fills my mother's head with nonsense about me and my mother believes it. She will start arguments with me and then turn it around into an argument with me and my parents by which time she go into another room and sit and laugh at us.
It is getting to the stage where I am starting to take a massive dislike to her. I have tried to get along with her and I do get along with her but she has this vendictive side of her that is difficult to handle. She protrays herself as an innocent quiet young girl but this is not how she is at home when around family, I am fed up of people taking her side all the time, people do not know what she is like.
But we haven't even met!
