The statement, "talk is cheap" goes hand in hand with watching what a person does. Years ago, a person's word was their bond. If a deal was "struck" and people shook hands on the agreement it was as good as gold. No attorneys were required, no long documents; a man's word was binding. In "those days," a person's integrity meant something to them. Most would rather die than lose their good name.
Unfortunately, a person's word does not mean what it did in the past. People will say anything to get what they want regardless of the truth of their statement or the intentions and motives they possess. In most cases, it is wise to watch what a person does before listening to what they say. It is disappointing that the virtues of honesty and integrity are taking such a beating.
