Its foolish to think that anyone can sum up, or appropriately configure OUR OWN behavior,and how it arose. You do state the obvious however, that it depends on the surrounding's,and how a person was raised, etc. Anyone with some sense can tell you that. I can tell you that if anyone had the correct answer, It would'ent be one of us. but i think if it were a report to be graded, you'd get an outstanding grade, based on the fact, that we humans are so stubborn as to think we can try to explain the unexplained. Sorry, if i have offended anyone, these are my belief's.go me.
