Even if we knew every language and used all the words, hand gestures, and facial expressions possible, we would still misunderstand one another. Therefore, it is so important to do what we can to understand and be understood. So try to say what you mean and mean what you say, especially the things that are hard to talk about. One effective tool while communicating, especially during a disagreement, is to try to understand before trying to be understood. Often two people will be trying to get their own point across, yelling over one another, neither being heard. Once a person feels understood, suddenly they will be open to understanding the other. Open the door of communication and try understanding first. Hint: ask questions until you really get where they are coming from.
