Often times we under estimate the power of space when we are in an argument. If you find your self getting frustrated ask your self a few questions:
1) Am I a close talker when I’m in conflict?
2) Do I naturally move closer when I’m frustrated?
3) Is the person I am talking with noticeably uncomfortable with my proximity?
If the answer is yes to any of these questions, you might be sending an unconscious signal to the person of intimidation. If you find your self in a similar situation, take a step back and leave the situation to avoid further conflict.
