I quarreled with my aunt. What should I do?

Maybe your aunt's thoughts are conservative. She doesn't like girls falling in love so early (I think you are a woman, too) and thinks that you have taught your cousin a bad lesson. In fact, you shouldn't quarrel with her at this time. After all, she is your elder. But things have happened, and your relationship with your aunt will become more and more rigid. At this time, you should ask your parents to help you explain. You should take the initiative to apologize to your aunt. After all, everything at home is happy. The more rigid the relationship, the more dead the road.
