Shut up by Lucky Dube is full of wisdom! Everyone who likes gossiping and making enemies should listen to it very carefully. Everything you do in life will come back to you, whether good or bad. You'd better be good to everybody you meet: Even if it doesn't seem so now, you might depend on the person's help one day.
don't say those words that will hurt people don't do those things that will hurt people the things you say today will come and haunt you tomorrow the things you do today will come and haunt you tomorrow
