GEN1556 Even if you are overcome with emotion, you must be careful not to cause anyone embarrassment.   … Yosef’s self-control was amazing.   He was overcome with emotion and unable to withhold his identity from his brothers any longer.   Nevertheless, he did not become confused or allow emotions to overcome his reason.  Yosef did not reveal his identity until he had dismissed all the Egyptians from the room in order that his brothers should not be shamed by a recounting of their sin in the presence of others (Rabbi Yehuda Leib Chasman in Ohr Yohail, vol. 2, Vayigash). Very often when people are emotionally excited, they become so confused that they entirely forget about the feelings of others and are apt to embarrass them.  We must be on our guard not to shame anyone, no matter what the circumstances.   PLYN 120
