Disclaimer: I don't own the characters, just the ideas in their heads.
Growing up she was a good kid. She got straight A's. She never fought with her parents. She got along well with her sister. She gave more gifts than she received. Quinn Fabray was simply a good kid.
Quinn never missed curfew, except that one time, but she called her parents to tell them she would be late so it doesn't really count.
Quinn never skipped class, except that one time, but there was a substitute and he didn't care that she left so it doesn't really count.
Quinn never drove recklessly, except that one time, but the Beatle just hit a snow bank and no harm was done so it doesn't really count.
Quinn never stole anything, except that one time, but she was young and it was just a piece of candy so it doesn't really count.
Quinn never lied, except that one time, but it was only to protect Finn's feelings because she knew he would be a good father so it doesn't really count.
Quinn never drank underage, except that one time, but she was feeling fat that day and she didn't get caught so it doesn't really count.
Quinn never got pregnant, except that one time, but it was a mistake and she gave the baby up to a wonderful mother so it doesn't really count.
Quinn never cheated on her boyfriend, except that one time, but she was drunk so it doesn't really count.
Quinn never cheated on her second boyfriend, except that one time, but Finn stood up for her and helped her to make the right decision so it doesn't really count.
Quinn never hurt anyone, except that one time, but Rachel deserved to be slapped for trying to steal her boyfriend again so it doesn't really count.
Quinn never killed anyone, except that one time, but she didn't see Rachel cross the street as she was texting Santana and it was a complete accident so it doesn't really count.
She really was a good kid if you look past all the exceptions, but they don't really count do they?
