A gentle answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise adorns knowledge, but the mouth of the fool gushes folly.
Have you ever tried to argue in a whisper? It is equally hard to argue with someone who insists on answering gently. On the other hand, a rising voice and harsh words almost always trigger an angry response. To turn away wrath and seek peace, choose gentle words.
