Nikolai Gogol,
Dead Souls — Part I, Chapter VIII
“ Chichikov stood rooted to the spot, like a man who, after issuing into the street for a pleasant walk, has suddenly come to a halt on remembering that something has been left behind him. In a moment, as he struggles to recall what that something is, the mien of careless expectancy disappears from his face, and he no longer sees a single person or a single object in his vicinity. In the same way did Chichikov suddenly become oblivious to the scene around him. ”
