I think we have all been too quick to speak out in anger when hurt by another. I know I have. Words cannot be taken back. You can apologize and should do so when you find that you have let negative emotions drive you to say things too quickly. However, those words have been spoken and will always resound themselves. Pray for grace and God can help us all overcome.

Do not let yourself speak in anger or resentment that may you feel
For those words are clouded with these emotions.
These words make wounds that may not heal.
Think about what you say and save the dire commotion.

Consider why you feel these things and diligently search your heart.
If you take the time to search you may choose your words with care.
You may choose to speak with forgiveness, a more creative start.
Anger clouds your judgment and thus your words will be unfair.

Love will be the catapult which will help you rise above
You can lift over the need for angry words and resentment.
And search within your heart and soul for capacity to love.
If you do this you will save your self the agony and replace it with contentment.

Your soul will sing praises to his holy name
And you will commune with him with peaceful mind.
If love and forgiveness is what you give, you will surely receive the same.
Love breeds love, that.. forgiveness and brotherhood are the tides that bind.

It is better to live and love and forgive
It is better not to carry the heavy burden of hate.
For this burden will become heavier for you with every day you live.
Apologize and make amends with your brother or sister before it is too late.
