I tend to avoid confrontation. Many times it is because I am able to “put myself in their shoes”. I can understand where they are coming from and so can accept or adapt to the situation as it presents. I also tend to live in my head so I do not even notice things that may irritate others. That is my style. It is important to know your style and, if possible, the style of the person you are going to be conversing with. Do you run from confrontation? Do you get super defensive? Do you shut down?
As I approach a conversation that may become emotional and involve disagreement, I try to be mindful of my purpose and creating a safe atmosphere. It can be helpful to give the person a heads up about the discussion. You can schedule a time to meet with them. If I approach a person the wrong way, perhaps when I am angry, they will likely shut down or get get defensive and start yelling back. This will not accomplish anything!
