Actions speak louder than words. Angry words fan the fire like wind. To call a spade a spade. Do as I say not as I do. Few words and many deeds.
Gossips are frogs, they drink and talk.
If you don't say it you will not have to unsay it. It takes two to have an argument. Keep your mouth shut and your eyes open. Many a true word spoken in jest. Silence is an excellent remedy against slander.
