All of us have people who irritate us. We are tempted to lash out them and "give them a piece of our mind," but the best course of action is to leave the alone. Solomon the wisest man who ever lived had this to say Proverbs 29.
"If a wise man contends with a foolish man, whether the fool rages or laughs, there is no peace." In other words, there is no talking sense with some people, so best leave them alone.
"A fool vents all his feelings, but a wise man holds them back." Here Solomon advises it is never good to fully express your disastisfaction. Hold your peace.
As I write these words I acknowledge I am frustrated with a couple of people. I have thought about reasoning with them, but I have tried that before. I have also briefly thought about really unloading on them and telling them how disappointed I am in their behavior, but I realize nothing good will come out of me scolding them. So I am left with the words of Solomon. I must hold my tongue, move on, and try to be a person of honor.
