Sure, being a good friend is a menschy thing to do--but it's also a very Jewish value too!
Judaism has long recognized the benefits of friendship. In the Book of Ecclesiastes, it actually says: “Two are better than one. For should they fall, one can raise the other; but woe to the one who falls and has no companion” (4:9-10).
And Jewish sages encourage everyone to develop at least one close friendship too (seriously, check out Pirkei Avot).
Good friends speak to one another respectfully, listen empathetically, and develop the abilities to compromise, cooperate, and forgive.
