a) Strive to edify your school–mates by your good example at all times. Greet your friends and classmates. In fact no sermon is more efficacious than good example.
b) Never make fun of those who are backward in their studies or anyone with a physical defect. What you laugh at or despise in others may someday befall you.
c) Gladly help one another and let there be no selfishness.
