Anton Chekhov said this quote

In short, the man displayed a constant and insurmountable impulse to wrap himself in a covering, to make himself, so to speak, a case which would isolate him and protect him from external influences. Reality irritated him, frightened him, kept him in continual agitation, and, perhaps to justify his timidity, his aversion for the actual, he always praised the past and what had never existed; and even the classical languages which he taught were in reality for him goloshes and umbrellas in which he sheltered himself from real life.
