How do you deal with a secretive sister?

Some people are just like that. They don't want other people knowing about their personal lives and what not. It's not so much that they could be keeping a secret, they could just be uncomfortable discussing such matters.

I am wondering how old your sister is. If she is a teen yet, talk to your parents about this. It is really more their place than yours to find out if something is wrong in her life. How long has she been like this? Is this secretiveness a change in behavior for her? Or has she always been more of a private person. Not all people want to share everything with others. And this is not 'wrong' its just different. I personally don't like sharing some information. Just because people happen to be in the same family does not give them the 'right' to know everything about you, from the numbers on your blood tests, to the numbers on your scales, to the numbers in your checking account.

Really it is her right to be secretive. Maybe she is so because everyone is so interested in her business. I am sure that if you give her space and let her know that you are there for her, she will share things if she wants to.

My sister too is very secretive. Like you, she's the only family member who doesn't want to share stories. She doesn't want us to touch her mobile phone, we don't know anything about her friends, we don't know if she has a boyfriend,etc. One day, she just went away and we don't know where she went. But still she comes back whenever she's out of money. She has done already three times. I call her "stow away girl" because she's doing everything just to be with her friends. I can't understand her. Why can't she survive my parent's strictness. They aren't that strict anyway.

Yes! There are people like this. Like they say, there's always a black sheep in the family. And maybe she's so secretive coz that's the way she wants things to be. You can't expect everyone, even your own sister, to open up.

Hmm i think your sister is interovert, i think she likes privacy and, peace. She doednt like any one to invade in her personal matters. She might be hiding her mobile and other personal things, because she dosn't know wat kind of response she will get from you or your parents regarding her friends, so she wants to keep secrets away from you peopla ears. so i suggest you to first make her fell that sharing screts with you will not bring any harm to her, like u wont go and open up her screts in front of your parents. First start by telling your scereats to her, and asking her suggestion. in that way she will be happy that you are considering her as your good friend, and soon she will be closer to you
