"Many times when logic steps in, common sense takes a holiday." - Lady of Light
Logic and Common Sense do not go hand in hand. Logic is what is taught as a way of thinking to come to a conclusion, whereas Common Sense is a natural way to come to a conclusion. Logic is not always the right way to go. Sometimes (most times) we need to use our common sense when coming to logical solutions. If logic and common sense cannot work together, then the logic is flawed.
