I have helped her, though, I am regretting it, she's selfish, my sister, she cares nothing about herself, it's just, I hope she could grow up and find a better life for herself, instead of working hard, spending all her money and then asking other people to help her out, but like you said, I helped her, thanks for being here with me, you really mean a lot.
Never mind. you did your best! please, don't regret about it. one day, I think she will grow up and have a best life like you wanted. It's just hard to be an adult. you should give her time to think and learn.
