GEN1515 We should try to cheer people up when we see that they are despondent.   … When Yosef noticed that Pharaoh’s officials were dejected, he asked them the cause.   Yosef had good reason to keep to himself and concern himself only with his own welfare.  He had been sold into slavery by his brothers, and now he was in prison due to a false accusation.  Nevertheless, he cared about his fellow man, and when he saw someone with a problem he was eager to help.  The Chofetz Chayim writes that although it is usually commendable to speak as little as possible, it is a moral obligation to boost the spirits of someone who is dejected, by conversing with him at length.
