Finding yourself needing to correct someone puts you in a delicate place in a relationship.
If the person’s conceited, you will only be insulted by them when you offer your suggestions. They will end up hating you. If you correct an evil person, you will definitely get hurt. Pray that you are only tempted to correct a wise person for they will respect you.
Not sure many wise people are around – try to hold off any temptation to correct anyone but yourself. If you respect yourself afterwards, I believe that makes you wise.
