I have sister who seems to think she owns certain things, so if she does it/owns it/wears it no one else is allowed to. Examples are she bought something in her house and I commented that I liked it and that I might get one and she said I wasn't allowed to! Another is she uses a certain website to buy clothes and said no one else is allowed to shop on there, they are going out type dresse s which I don't go out clubbing anyway but she said if I ever wanted to she would "let me" choose one of the dresses from there. When a friend was admiring the dresses and asking where she got them from she cut the tags out of the dresses so she wouldn't she got them from. Now the recent thing is she has use glitter wallpaper in her room (very common at the moment and I know not to everyone's taste) i wanted to do it to a wall in my house and she has said I'm "not allowed" because it's " copying " wibu to ignore her. I realise how immature this sounds but this isn't coming from a 30 yr old woman.
