Personal Logic

So I keep wondering about the wiring in everyone's head. Do we each have our own logic? I understand we are all shaped differently in life, which ultimately in turn will shape our logic. Some people stick to an over riding code from religion to what their parents tell them to what they see on television. Some of us pull our logic from a variety of places. Generally you end up hanging out with people with similar logic. Maybe one of these people strikes your fancy and you start dating and so on. What I do not get is when these situations go crazy because the logic starts to break down. I probably do not get really comfortable with a person until I understand their logic partially or at least thing I do. Obviously I missed bits and pieces crucial to the whole puzzle. These are the same bits and pieces I see in movies that result in unpredictable behaviors and end just as bad. See the thing is the angst and frustration that also result could have all together been avoided had someone just come out and explained what was going through their head. Oh well...just means a search for a new person with a new logic is about to begin.
