It was plain to them all that Colonel Fitzwilliam came because he had pleasure in their society, a persuasion which of course recommended him still more; and Elizabeth was reminded by her own satisfaction in being with him, as well as by his evident admiration of her, of her former favourite George Wickham; and though, in comparing them, she saw there was less captivating softness in Colonel Fitzwilliam's manners, she believed he might have the best informed mind.
But why Mr.Darcy came so often to the Parsonage, it was more difficult to understand.

It could not be for society, as he frequently sat there ten minutes together without opening his lips; and when he did speak, it seemed the effect of necessity rather than of choice--a sacrifice to propriety, not a pleasure to himself.
