"The one keeping his lips in check is acting discreetly." (Prov. 10:19) ~ ???

Good communication does not mean saying everything you are thinking and feeling at any given moment, especially if you are upset. The Scriptures show that uncontrolled expression of anger is a mark of weakness, not of strength. (Prov. 25:28; 29:11) 

Moses—“ by far the meekest” of all men then alive—once let the rebelliousness of the nation of Israel cause him to lose his temper and fail to give glory to God. Moses very clearly communicated how he felt, but Jehovah was not pleased. After 40 years of leading the Israelites, Moses did not have the privilege of taking them into the Promised Land. (Num. 12:3; 20:10, 12; Ps. 106:32) 

The Scriptures commend the exercising of restraint and discretion when we speak. (Prov. 17:27) Yet, discretion does not mean never expressing oneself. It means speaking “with graciousness,” using the tongue to heal rather than to hurt." (Prov. 12:18; 18:21; Col. 4:6) - Bible Speaks - jw.org
