" Vous eprouves trop d'emotion, Hastings, It affects your hands and your wits. Is that a way to fold a coat? And regard what you have done to my pyjamas. If the hairwash breaks what will befall them?'
'Good heavens, Poirot,' I cried, 'this is a matter of life and death. What does it matter what happens to our clothes?'
'You have no sense of proportion Hastings. We cannot catch a train earlier than the time that it leaves, and to ruin one's clothes will not be the least helpful in preventing a murder. "

― Agatha Christie , The A.B.C. Murders (Hercule Poirot, #12)
