I commute to work daily on a bus for about an hour each way. I think I am pretty good with dealing with all types of things but today someone sat next to me on the bus at 6am and had music blaring from their headphones. I assumed they didn't know how loud it was and kindly asked them to turn it down a little. They turned to me and said "thats not my problem". I was shocked at first but then angry but did keep my mouth shut although I had 100 things to say. Should I have said something else? Is it ok to accept rudeness and be fine with it?
