I have often remarked in the United States that it is not easy to make a man understand that his presence may be dispensed with; hints will not always suffice to shake him off. I contradict an American at every word he says, to show him that his conversation bores me; he instantly labors with fresh pertinacity to convince me; I preserve a dogged silence, and he thinks I am meditating deeply on the truths which he is uttering; at last I rush from his company, and he supposes that some urgent business hurries me elsewhere. This man will never understand that he wearies me to extinction unless I tell him so: and the only way to get rid of him is to make him my enemy for life.
