Fact is, there's two sides of this. One sides is telling at least a partial truth. The other side is probably telling the partial truth. We only know what we're told. None of us have a crystal ball to see actually what happened?
Was the woman telling the truth? Or was the young man telling the truth? Were both of them lying just a little, with enough truth to make their stories seem factual?
Who knows?
So then, we pick a side to believe and just go with it.
Question is, why do we choose to believe one sides over the other, when all we have to go on is what we're told?
