“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.

“Of course. I understand.""One of your brilliant mentality could not fail to do so, Hastings.”
“No, my friend, I am not drunk. I have just been to the dentist, and need not return for another six months! Is it not the most beautiful thought?--Poirot”
