Earlier today, my sister and all of her friends tried out for a musical audition and each for different parts. All of my sisters friends got callbacks but my sister did not. Her one friend said something to her that to me sounded really rude, and I did not want anyone to treat my sister that way. So I reached out to my sisters friend who I follow on instagram, and told her how I felt she was treating my sister and that true friends don’t do that. She replied back that I was sticking my nose in someone else’s business and that she would never do anything to hurt my sister. I apologized for accusing her, and we were cool. Then she told my sister what I had originally said to her, and now my sister is mad at me, really mad. How to I patch things up with my sister?
Your sister should be grateful for what you do. Don't feel bad about it because what you did is love for her and your actions are also right. The problem here is her friend is not open-minded enough and bitchy (excuse my word) to tell you like that. You are her big sister and you have the right to protect your lil' sister.
For you to pacify this, you can write to your sister a letter saying your intention about it. You can also apologize but if they don't accept it, be it. Over time, when they grow older they will realize what you did is right and you are just concern. You don't need to please everybody else.
1. Write an apology letter
2. Offer her a gift to compensate for the misunderstanding
3. Talk to her friend about it
But if it doesn't work. Try to ignore them and live with it. Soon they will realize their close-mindedness and reconcile with you. You did not do wrong. They are just young to understand things.
