Nikolai Gogol said this quote
“ He never looks you straight in the eye; or if he does, it is somehow vaguely, indefinitely; he does not pierce you with the hawk's eye or the falcon's gaze of a cavalry officer. The reason for that is that he sees, at one and the same time, both your features and those of some plaster Hercules standing in his room, or else he imagines a painting of his own that he still means to produce. That is why his responses are often incoherent, not to the point, and the muddle of things in his head increases his timidity all the more. ”
