This admirable person would have been completely happy but for the numerous interruptions to his studies caused by folk who came to consult him about their troubles (in which he was not interested), and by the loud knocks of the iceman, the milkman, the baker’s boy, the laundryman and the peanut woman. He never dealt with any of these people; but they rapped at his door every day to see him about this or that or to try to sell him their wares. Just when he was most deeply interested in his books or engaged in watching the bubbling of a cauldron there would come a knock at his door. And after sending the intruder away he always found he had lost his train of thought or ruined his compound.
