A gilrfreind lies for a year to her in-laws about her job, telling them she's a nurse and works at a hospital. On the one night they meet her sister, they ask her about it and she accidentally reveals the girlfriend actually works as a receptionist at a dental office. 

How can you protect a secret you don't know is being kept?

Many times in life, you rely on your siblings to keep your secrets. They usually are the people who know you the most, with whom you share your deepest fears, and who are there to back you up when you make a mistake and need some help without mom and dad finding out. Siblings cover up for each other all the time. I'm not saying athat keeping things from their parent's is okay, but when they are teenagers that is somewhat normal and expected. As long as they both know when to stop covering each other up to get the appropriate help they need, is normal sibling behavior. 

However, when they reach adulthood, having to cover each other up for their mistakes and lies shouldn't be the norm. When you grow up, it shouldn't be necessary having to lie to others about certain aspects of life, and much less having your sibling lie alongside you. 

Apparently, not all people think that way, because this young woman got upset at her sister for not lying and covering up for her, even though she had no idea she had lied about such a mundane topic.

  • I found out the next day what I'd done. She'd been telling his family for 6 months she was a nurse. I blew a year of that up in a sentence.

  • There's so much about this whole story that makes absolutely no sense. In fact, I have more questions than anwers at this point. For starters, why did the first sister lied to her in laws in the first place? It's not like she's the first person ever to drop out of college, and her current job is perfectly normal and respectable! If she did it just because she wante to make an impression, then she's even more immature than I had thought. Besides, for how long did she think she could keep up the lie? Once someone started asking even the most normal of questions about her job they would realize she had no idea what she was saying. It's not even that she had an embarrassing or morally questionable way of making money to have to lie about it. And if she was goint to do it, she should have planned it out better and told her sister beforehand what to answer. 

    And one more thing, how is it that her mother in law ended up talking to her sister alone and asked about her own daughte in law's job? That interaction sound so random, why wasn0t she there to do amage control? One thing is for sure, asking her to call and lie is one of the most exagerated responses. Other than that, does she think her mother in law is that dumb not to realize someone ther is lying? This girl is clearly nothing remotely close to a mastermind. 

    The whole issue sounds hilariously ridiculous, and I hope the girl learns her lesson about saying random and silly lies when there's absolutely no necessity. 

  • According_Leg_374 You literally did not know she was lying. His mom asked you a normal question and you gave a normal answer, you cant protect a secret nobody told you about ΝΤΑ

  • Next-Drummer-9280 You didn't know your sister was lying to them. But this: I'm no stickler for the truth. is not the flex you think it is.

  • Sufficient_Song3387 Nope. Stay out of ot now. She would never believe you now. His family will just think that she's manipulative on top of being a liar.

  • Frankifile Anything you do now will just dig the hole deeper. I wouldn't believe the sister does not know what her sister does. I'd just think you were also a liar and would not trust you either. Stay away from this.

  • cthulularoo Cats out of the bag now. This is all on her. Even if you try to fix this, his mom isn't stupid. All it takes is for her to ask sister to lunch at the hospital. Your sister is finding out that real life isn't a sitcom. NTA
