why do girls lie all the time well i can tell you something that bugs me so bad about my sisters and their friends they lie about everything everything and they always get away with it for example my sister threw a shoe at me it slammed into my face and she claimed it hit me in the stomach how the crap would she know she wasn't the one that got hit anyways when they lie they do get away with it which is why i'm going to answer this question now girls lie so they don't have to get in trouble girls hate getting in trouble and then they rebel when they get grounded and a lot of fighting goes on also they'd always rather have their friend or another person in trouble but them so take this for example tashya made up the name does something bad and she knows she'll get in trouble for it so when her mom or dad finds out she blames it on her brother and her brother gets yelled at and grounded for her fault girls also love it when other people get in trouble so i answered my question
