She is the most naive n innocent girl in there..I understand her and the positions she takes in the house..
Of course she has insecurities coz of the issues she has faced in life but she is fiercely loyal to her friends. Sid calls her bin painde ka lota, jiske saath baith ti hai uski burai karti hai..but does he understand why she did that?
Sid is her friend, most probably from before BB so of course she has seen the better side of Sid... if she felt that Sid should know how he is perceived by people bcoz of his behaviour, she was absolutely justified in telling this to him..
she told coz she cared enough about Sid's image, not coz usko idhar ki baat udhar karne ki aadat hai..ye simple si baat us gadhe ke samajh me nahi aati aur wo baaki contestants ko gadhe bolta rehta hai..
He doesn't deserve a friend like Arti..he may be a fun loving, jovial guy during normal good days but the side of him that comes out in pressure situations is scary..don't know how anyone can be with him for longtime.
But Arti ki problem aur hai..guys usually like funny , easygoing girls jiske saath wo masti mazak kar sakte hai..jo zyaada complicated na ho, insecure na ho..and most of all those who don't advice them or show extra care..men feel they can handle things on their own and don't need advice.
Arti isn't a girl like that..she cares and goes overboard so is taken for granted. Plus she is sensitive..that explains why she doesn't have many male friends in the house..Sid was a friend so she was close to him and had expectations from him..but the guy turned out to be such n insensitive prick
