My friend said that I know the ambitions of a swan. How should I respond?

Your friend said: How can a sparrow know the ambition of a swan?

You should say to your friend: How can you know the joy of a sparrow if you are not a sparrow? You now have ambitions to fly like a swan, but you spend your days hanging out with sparrows. How can you have such ambitions? I think that this swan is just like the frightened bird, how can it be compared with my sparrow? I think your ambition is the ambition of a mediocre man. How can it be the same as the swan spoken by the ancients?
