Never say mean words out of anger. Your anger will pass. But your mean words can scar a person for life. So use kind words or be silent.
“When the person you love can't see your love for them beneath the painful things you say when they reject you, remember this: Love is blind.”
― Shannon L. Alder
"Be careful with your words. Once they are said, they can be only forgiven, not forgotten." -Unknown
"Be careful what you say. You can say something hurtful in ten seconds, but ten years later, the wounds are still there." -Joel Osteen
"If we understood the power of our thoughts, we would guard them more closely. If we understood the awesome power of our words, we would prefer silence to almost anything negative. In our thoughts and words, we create our own weaknesses and our own strengths. Our limitations and joys begin in our hearts. We can always replace negative with positive." -Betty Eadie
