Best time for us to hold our tongue is, when we really feel like, we must say something to those, about their; ungratefulness, meanness, ignorance, foolishness or whatever; because our words can create or kill, begin or end, win or lose, welcome or banish. So be wise, be patient.... My friend it is very east to break, kill and destroy... Words are more powerful than anything... Our words carry life and power... USE them but NEVER MISUSE them....
