I am so angry at my sister right now. I mean she never does her homework and yet she still plays computer and have fun no matter how mad my dad is about her homework. I do so much things to get her out of trouble, give her extra time to finish her homework, and I do so many errands just because my parents want to let her finish her homework. And she always ask me how to finish this homework and I always end up telling her the answer just because I can’t stand the thought of letting her ruin my weekend watching movies; just because she didn’t finish her homework. No matter how hard I try to make her finish she never does. What should I do? I’m so tired of always have to wipe her b*** for her and getting her out of sticky messes that she made herself.
