Gentleness, Gentleness, Please

Lord, please put a guard over my mouth and help me to use more soothing and gentle words with those who may not understand exactly what I am trying to convey.  Give me wisdom in my words today as so much can be mis-understood or maybe it is just not comprehended and I have a tendency to raise my voice and can get impatient at the outcome that I have expected.  Keep my expecteds in proper perspective because sometimes, I just plain get so frustrated and inwardly I am throwing a tantrum like a two year old which would be a shame & damage to my witness if my thoughts were exposed.  But you, God, you know everything, so for these improper thoughts, I must ask forgiveness.
