Fighting

Everyone hates to get in a fight with a good friend.
The best thing to do when someone is mad at you is to go to them first. They will tell you the real reason why something is bothering them. And if you go to other people first they can mislead you and possibly tell you the wrong reason why your friend is upset.
A good friend will appreciate that you came to them first. And try to be openminded when they tell you what the problem is!
