Sometimes, it is very hard to express what one is thinking. Thoughts don't always translate into words, exactly what one wishes to convey, and words are very powerful. That's why it is so important to think before speaking, I suppose.
I am not a poet, but here are some words that came to me one day while feeling a little wounded by some words that were spoken:
A word is such a powerful thing
It can lift a heart, or break it.
Be very careful what you say
Once said, you can't retake it.
It could be the reason, too, that my very wise mother, and grandmother, said to me, "If you can't say anything good about someone, don't say anything at all."
What a wonderful world it would be, if we would remember to speak only that which is good, and uplifting, and encouraging, so that our words become a blessing, rather than a burden.
Finally, brethren, whatsoever things are true, whatsoever things are honorable, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
