Hell hath no fury like a little girl scorned. And this little girl is making no bones about her beef... which is that her sister is eating all the food, and her friends' food, and possibly her future husband's family too. Wow. The girl launches a scathing attack on her big sister telling her that she will acknowledge her as her sister only when she "stops eating all the food". Thankfully, her big sis Louisa isn't the sensitive sort, and posted the note to Facebook with the caption: "I swear she's a little brat. I don't even eat that much so I idk what she's talking about. Fully draws the finger too." The letter in full reads: "To my fat sister Louisa. "I hate you because you eat all our food for lunch and you always say it’s not you but you are always in the kitchen, you fat cow. "That’s why you have no friends – because you eat their lunch too, you dumb fat girl. That’s why your bum is fat because you eat all the food. "I hope no one marries you because you might eat his family too. "I will you call you my sister when you stop eating our food. "Bye ugly girl, I still hate you!"
