The last thing we want to do is fight. Sometimes it is hard to keep peace, but unless you do you're going to get yourself in one big mess. Even if peace to you is getting along with your friends or teachers it is still important, cause one day you might be stuck working together. Everyone is born with anger, so no one can be wrong in feeling it. There is just a certain way of expressing it, so that you don't offend someone else.
Many countries have peace problems fighting over land, property, religon, and government.
If everyone had the ability to compromise than maybe people would get along better. Until then we have to try as hard as we can to keep the peace.
