I use to for peace of mind to be cool with everybody. But being cool with everybody is not always the best thing especially once you move on to be in a better place. Some people ways don’t change, and some people don’t forget the past, and they live there instead of moving forward. So at first you think you’re doing a good thing, but it always ends up reminding of the past in a bad way instead of good. But every situation is different but similar.
