It is normal for friends to joke with each other. When everyone is like-minded, talking and laughing, and relaxing, the friendship between each other will be enhanced. But sometimes you may accidentally touch on other people's sensitive topics. At this time, you should restrain yourself. If you really offend your friends, of course you should apologize properly. Here are some suggestions for you:
First, give her a fun little gift, a crystal music box. Good music will slowly make her calm down. You can also give her a cute shy bear doll. Girls will like such cute gifts very much. I believe that she will turn her anger into a smile.
Second, give her a gift she likes. Since it is an apology, you should be sincere. For girls, you can give her a small perfume. The fragrant smell will also make her feel better and she will forgive you.
Third, give a bouquet of flowers to represent your deep apology. Apologize properly. I think good friends will not bear grudges against you.
These are some of my suggestions. I hope you can adopt them.
