Man is the only slave. And he is the only animal who enslaves. He has always been a slave in one form or another, and has always held other slaves in bondage under him in one way or another. In our day, he is always some man's slave for wages, and does that man's work; and this slave has other slaves under him for minor wages, and they do his work. The higher animals are the only ones who exclusively do their own work and provide their own living.
Mark TwainI am dead to adverbs; they cannot excite me. To misplace an adverb is a thing which I am able to do with frozen indifference; it can never give me a pang. There are subtleties which I cannot master at all - they confuse me, they mean absolutely nothing to me - and this adverb plague is one of them.
