Chinuch Hora'ah of the Day:
Family life that is good and frum, and the refined manner in which husband and wife relate to each other – in addition to being one of the mitzvos that Hashem has given us the privilege to fulfill – is indirectly also the best chinuch, which influences the children and ingrains in them the best possible middos (character traits).
