Что делать?

[timelets]

При чтении Дон Кихоте у меня постоянно возникает вопрос: Что делать, когда встречаешься с человеком, который говорит, выглядит и действует, как сумасшедший? Особенно, когда он грозит тебе копьем?

“Don Quixote raised his voice and, striking a haughty posture, declared:

‘You will none of you advance one step further unless all of you confess that in all the world there is no maiden more beauteous than the Empress of La Mancha, the peerless Dulcinea del Toboso.”

The merchants halted when they heard these words and saw the strange figure uttering them, and from the figure and the words they realized that the man was mad; but they had a mind to stay and see what would be the outcome of the required confession and one of them, waggish and sharp-witted, said:

‘Sir knight, we don’t know who this worthy lady is; do let us see her, because if she’s as beautiful as you claim she is, we’ll most freely and willingly confess that what you say is true.’

‘If I were to let you see her,’ retorted Don Quixote, ‘what merit would there be in confessing so manifest a truth? The whole point is that, without seeing her, you must believe, confess, affirm, swear and uphold it; if not, monstrous and arrogant wretches, you shall face me in battle forthwith.”

Miguel de Cervantes. “Don Quixote.”
