The world is full of obvious things which nobody by any chance ever observes. My name is Sherlock Holmes.  It is my business to know what other people don't know. Education never ends, Watson. It is a series of lessons, with the greatest for the last. I have always held, too, that pistol practice should be distinctly an open-air pastime; and when Holmes, in one of his queer humours, would sit in an armchair with his hair-trigger and a hundred Boxer cartridges and proceed to adorn the opposite wall with a patriotic V.R. done in bullet pocks, I felt strongly that neither the atmosphere nor the appearance of our room was improved by it. I must apologize for calling so late, and I must further beg you to be so unconventional as to allow me to leave your house presently by scrambling over your back garden wall. Is there any point to which you would wish to draw my attention? To the curious incident of the dog in the night-time. The dog did nothing in the night-time. That was the curious incident 
That's what it said on 'Ask Jeeves.' Marry me. 

Next time you want to stab me in the back, have the guts to do it to my face. Well, my time of not taking you seriously is coming to a middle. How did your brain even learn human speech?
