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?
