A soft answer turns away wrath.

Communication is very much essential in maintaining a harmonious relation, it cultivates a lasting bond that binds. But often the situation change and differ, that we can't control ourselves in uttering harsh words to our fellow in a conversation, if we want to identify and insist we use high pitch of voice to command and force them to follow. Then the nice relation would be affected, and will be failing to continue.

The books of Proverbs has something to say about words and answering to our fellow, which will be effective if we consider and do it nicely, it took some effort for one to be intelligent enough to handle his own words and temper in a conversation, it says in Proverbs 15:1, that, "A soft answer turns away wrath, but a harsh words stirs up anger."
Our words are the outlet of human emotions, but let us be careful in bringing out our words especially if we feel something against the person whom we're talking. God is always good to us, He shows means for us to be in proper way in not proper situation.
