Most of us when attacked quickly put on our amor and fight back. When attacked verbally, we are quick with a response (oh, yeah?!). When attacked physically, we quickly respond as well (well, I'll get you). Few of us actually stop and consider whether the attack was real or imagined. Why did the other person attack? Were they simply having a bad day and only spoke harshly to you out of frustration?
Was the attack justified? Did you do something to them and they are "getting even"? Did they only think you attacked them first because you originally responded out of frustration (at them or another)?
Many "wars" (personal) might be avoided if we stopped to consider why the "enemy" is attacking instead of suiting up to fight.
