How to get along with my sister-in-law?

Personally, I think it's your own problem. Your sister-in-law is still ugly after a hunger strike. That's your brother's business, not yours. I think you are biased against your sister-in-law. Your brother is right to scold you. If a man is a man, he must cherish his wife and not let her suffer undue injustice. Think for yourself!
