1. She always wishes to be the center of attraction or is the elephant in the room

A narcissistic sister would do anything to establish their mere presence and seek attention by all means. They need constant attention and are desperate to gain it. They are the ones who are always showing off their achievements and talents. A narcissistic sister would always lay her ideas on top of yours, would collect all the praises from everyone, and be the center of attraction.

2. Everything is just about her

When you discuss your achievements or your needs with your parents, she would confiscate the attention and the topic and discuss how she had an excellent score or grades, or how she had informed you long back to get her something at the same time you demand something for you. For instance,

When you present your progress, to your parents, your narcissistic sister would immediately interrupt reminding everyone about her progress, or even worse she would be jealous and intimidated by you.

When you demand something from your parents, your sister would interrupt saying no, that she has demanded something first, and after she gets that it is your turn to get something.

3. She would lie recklessly

Narcissistic sisters would lie effortlessly when you ask the doubting something. They would even lie to their parents when they are unable to achieve something. Lying is the instinct of a narcissistic sibling. Narcissists have a very huge ego to satisfy, so they always want to prove a point even if it is by the means of lying. They just consider themselves smarter than others and thus lie recklessly. For instance,

When you ask your narcissistic sister about the money you lent her or the piece of clothing that you gave her to wear the other day, they would lie straight to your face denying that they do not remember any money or the dress. This is how they either hide their mistakes or just prove you wrong. And when you question them irrespective of their reply they would lash out at you, saying you lack trust or you are lying. This is how they even gaslight you.

4. She would be jealous of you

A Narcissistic sister would be jealous of your achievements, your happiness, or even your growth. If you surpass them in any way or by means they would not be happy about it and instead would degrade your achievement with jealous comments or criticism. Your narcissistic sister would just twist the reality of the situation. She would be abusive and irrational but would never accept it rather than keep denying it.

When a narcissistic sister gets envious of you, she would choose rivalry or humiliate you before your family members or friends, or acquaintances when you make them jealous or surpass their expertise.

5. She would think less of you or believe you are less important than her

When it comes to the emotional bonding of siblings or expect that you would be able to connect with your narc sister, you would not be able to as she would think less of you. She just considers herself to be superior, smarter, and ahead of you and thus there can not be an equal bond that you would expect from a sibling.

Even in front of your parents, she would constantly damage your image, or weigh you lesser than her. So in this case, do not go against her just keep proving yourself and you are good to go. A rivalry with a narc sister can be tough on you and can damage your bond.

6. She has a sense of entitlement

The sense of deservingness makes it difficult for a narcissist to go anywhere near the truth and reality. Fakes and lies make them look more promising and greater than others. Narcissist sisters feel they deserve everything special, and nothing less. This habit of entitlement does not allow them to look at the truth or the reality. They prefer lies as lies make them feel better, greater, and something more than others. They have their little cocoon of entitlement and expect that from others too. For instance,

Narcissist sisters think they deserve everything greater and better than you, so they are very demanding.
When a narcissist is proven wrong by someone, and when someone tries to tell them the truth, instead of facing reality they often tell more and more lies to cover up their mistake. They would gaslight you to the extent you feel guilty.

7. She would be inconsiderate of your feelings

There is no emotional bonding when you live with a narcissistic sibling. They have constant mood swings and emotional tantrums. So there is always a lack of emotional support and constant emotional manipulation. A narc sister would manipulate you to achieve anything she wants or wishes. She would use you as a tool just to be greater in front of your parents.

There is no meaning to the word sibling bond when you live with a narc sister. She would be verbally abusive and emotionally unavailable when you need her thus she is inconsiderate of what you feel and how you feel.

8. Her behavior would change when someone around other than you

A narc sister would behave differently around others, but when everyone is not around and it is just her and you, she would reveal her narc side and manipulate you. She would be all sweet, fake, and nice to you in front of others but mean, rude and inconsiderate when no one is around to watch. She would not want to reveal her narc side to anyone so she would play manipulative games and hide behind fake facades. She would talk behind your back to your parents and devaluate you in front of them.
