An umbrella is a necessary evil. A walking stick is a quite unnecessary good. This, I fancy, is the real explanation of the perpetual losing of umbrellas; one does not hear of people losing walking sticks. For a walking stick is a pleasure, a piece of real personal property; it is missed even when it is not needed. When my right hand forgets its stick may it forget its cunning. But anybody may forget an umbrella, as anybody might forget a shed that he has stood up in out of the rain. Anybody can forget a necessary thing.
