You should remember that other people possess the same feelings, as you possess, though they may not have the means to gratify them to the same extent as yon have.

Your words must be exceedingly kind. They must never wound his feelings of self-respect of justice. For, though he may not retaliate openly, yet his heart smarts under the pain, and is weaned away from you.
You should never cause mental, emotional, or physical injury to others. Their happiness is matter of sacred trust in your hands.
