My friend, Best time for us to hold our tongue is, when we really feel like, we must say something; because our words can create or kill, begin or end, win or lose, welcome or banish. Be wise, be patient [Proverbs 18.21] .... Many are in darkness or ignorance; not for lack of light or knowledge but they never open their eyes to information or knowledge. Remember wisdom and knowledge is must for improvement [Proverbs 1.7]
