List of points

Whenever you need to criticise, your criticism must seek to be positive, helpful and constructive. It should never be made behind the back of the person concerned.

—To act otherwise would be treacherous, sneaky, defamatory, slanderous perhaps… , and, always, utterly ignoble.

Put yourself always in your neighbour’s shoes. You will then see the various issues or problems calmly. You will not get annoyed. You will be understanding. You will make allowances and will correct people when and as required. And you will fill the world with charity.
