Recently I said something that offended my friend, I guess. It was nothing serious and I didn't have any intention to offend her. Whatever I said was in fun tone yet she is offended. I don't want to apologise to her because I don't think it's my fault. Her getting offended at small things is stupid. I have some self respect, why should I apologise for something I don't even see my fault for. She is mature she shouldn't be offended so easily at jokes. Am I right?
