Talented Tongue

I was recently talking to some friends and a couple of strangers.  During our conversation, the strangers turned to me and asked if I was a professional speaker.  I was confused by the question so I asked what made them think that.  They told me that I was a very eloquent speaker.  They said my words were powerful and meaningful.  I simply told them that I spoke the truth and from the heart.  The conversation made me do a little thinking.  I have been told in the past that my words are strong.  I have also been told that my words can cut deep like a knife.  Really makes you wonder about the saying "sticks and stones may break my bones, but words will never hurt me."
