Are they not the most wonderful and the most terrible things that we have at our disposal? Words. Words can start wars or end them. They can build or cause destruction. They can make someone's day, or ruin somebody's life. Words. Be careful how you use them. Once written or spoken, they can never be taken back, they will be used as reference and record to and for the the one that has used them, until the end of time.
Not for nothing has it been said that "The pen is mightier than the sword."
