1. First,  we should desire to be corrected before correcting others.
  2. Make sure that the person is at fault.
  3. Pray fervently for the person before giving the correction.
  4. Find the right time and place.
  5. TIME.  When the person is well-disposed: at peace and not tired and frustrated.
  6. PLACE. Never in public; this would be embarrassing!
  7. MANNER!  Always with charity. Remember the words of St Francis de Sales:  "You can catch more flies with a teaspoon of honey than with a barrel of vinegar.
  8. KINDNESS!  Before, during and after.
  9. Admit that you are the first to be corrected.
  10. Finally, after the fraternal correction has been done, pray for the person.   St Thomas Aquinas asserts that fraternal correction is a true manifestation of charity.
