Words, are both used to attack, and to defend. Words are used to deflate and to rise up. Amazing how words can have such tangible interpretation isn't it? They are a simple uttering of the voice, a sound created by air passing through the vocal tissues; and yet words can set things in motion like a finger tapping the first domino.
Never think that your words do not matter. Sometimes a person can be under such gloom that words seem ineffective; but give them a try anyway. Such a physically miniscule action, that has the potential for so much reaction, let us never take it for granted.
