Speaking in the sweet manner is very important. Some people think it is smart to speak in a rude manner or is very intelligent to shout on people, but no one likes this kind of a personality. You may be intelligent, you may be very sharp or smart, maybe on a television people may like to see you, but not as companions, as friends. To speak in a very sweet manner is a sign of good breeding, good culture and fear of God. Those who fear God will never speak rudely to another person, because in another person also the same spirit is shining and why should we be sharp or angry with another person who is created by God Almighty as we are created.
