Or according as he has come on foot or in a carriage, he rubs off or he does not rub off the slight patches of mud which soil his shoes.
Or perhaps he remains as motionless as a Dutchman smoking his pipe.
Or perhaps he fixes his eyes on the door and looks like a soul escaped from Purgatory and waiting for Saint Peter with the keys.
Perhaps he hesitates to pull the bell; perhaps he seizes it negligently, precipitately, familiarly, or like a man who is quite sure of himself.
Perhaps he pulls it timidly, producing a faint tinkle which is lost in the silence of the apartments, as the first bell of matins in winter-time, in a convent of Minims; or perhaps after having rung with energy, he rings again impatient that the footman has not heard him.
Perhaps he exhales a delicate scent, as he chews a pastille.
Perhaps with a solemn air he takes a pinch of snuff, brushing off with care the grains that might mar the whiteness of his linen.
Perhaps he looks around like a man estimating the value of the staircase lamp, the balustrade, the carpet, as if he were a furniture dealer or a contractor.
Perhaps this celibate seems a young or an old man, is cold or hot, arrives slowly, with an expression of sadness or merriment, etc.
You see that here, at the very foot of your staircase, you are met by an astonishing mass of things to observe.
