I hate my sister-in-law why?

There is nothing wrong with this, but everyone is happy to be kind to each other. This relationship is like a mother-in-law, and it is also an embarrassing role. Since your brother married her, she is a member of your family. This is something you must admit. You resisted from the beginning, and of course you didn't have a good face for her. She is your sister-in-law You should respect her and treat her as your sister. In this way, if she is a reasonable person, she will naturally be driven by you. If she still does this to you, it means she shouldn't. Now that she is an only child, it is inevitable that she has a little personality. However, we should inherit the traditional culture of China, respect our elders and be kind to others. You know, everything is a prosperous time with a family and talent. I wish your whole family happiness ~
