If you say, “That advice is wrong,” the giver will simply respond by explaining again why it’s right. If you say, “I disagree with that advice,” the giver can’t argue with the fact that you happen to have an opinion on the matter. You do. All that is left is to figure out why you see it differently. You might say this: “We had a different approach in the last place I worked, and we had fewer problems than we do here.”
