Do you hate your sister cause i do?

She is a major sl*t and im not making this up. She's older and im responsible for her and if she messes up its my fault. It also doesn't help that we are in the same grade and i here about everything she does and now people think im like her uhhh i tell her to act right but she doesn't see anything wrong with hows she's acting. Well all i want to know that im not alone and that its okay...
