Musar על יבמות 125:12

The ninth category is he who tells a story that he has heard, but he changes some of the narrative as he likes. Now there is no loss to any man in this, but he receives a bit of pleasure out of his lying, even though he does not gain any money out of it. For example (Yebamoth 63a), Rav would say to his wife, "Make me lentils," and she would make him peas — and whenever he would say to her, "Make me peas!" she would make lentils. Hiya, his son, went and reversed the matter. Whenever his father wanted peas, he would tell his mother, "Make lentils!" and she would make peas, and this the son did out of honor for his father, in order that there should be prepared for him the food that he wanted. Even so, Rav restrained him and persuaded him not to do this any more, because, "They have taught their tongue to speak lies" (Jer. 9:4). But the guilt in such a falsehood is not like the guilt of those who lie for no reason at all as we have mentioned in the fourth category.
