Proverbs 12:18 "Thoughtless words can wound as deeply as any sword, but wisely spoken words can heal."
I don't know about you, but sometimes... I forget to watch my mouth. I forget that my brand of humor, tough love, and candor can negatively affect someone, or possibly hurt them. I sincerely hope that I keep a good perspective, and speak good things to people that help them. Not intentionally, or snarkily just add hot air to the atmosphere.
