When Alice is talking to Humpty Dumpty, Humpty Dumpty says that he doesn't sing after singing the first verse of a poem for Alice. Alice responds "I see you don't." To this Humpty Dumpty remarks severely, "If you can see whether I'm singing or not, you've sharper eyes than most." This reminded me of the anecdote about Wittgenstein and his friend. The friend, who had just had surgery, says, "I feel just like a dog that has been run over." Wittgenstein gets irritated and says, "You don't know what a dog that has been run over feels like." Same impatience with slightly metaphorical usage.
