In marriage people get in fights because they don't communicate, because you don't want to hurt the other person. If you do want to hurt the other person, then shame on you - you're an asshole. My wife and I do not argue. We communicate. We talk. But we've never fought in our entire relationship.
I do tend to gravitate to the more dramatic side of things. I love feeling intense emotions when I'm acting. I just love characters and stories with conflict.
