In the presence of a man who thinks highly of himself, be very careful how you speak… Because while you speak, he interprets your words as he likes… and from your good words he finds an opportunity to scandalize others.
And he alters the meaning of your words in his mind according to his spiritual sickness. If you see a man coming and accusing his brother before you, make your face sullen. Thus you will have the mercy of God and be protected by Him.
St. Isaac the Syrian
