Nor have you, O poor parasite and humble hanger-on, much reason to complain! Your friendship for Dives is about as sincere as the return which it usually gets.

It must have often crossed Miss Crawley's mind that nobody does anything for nothing.

If she measured her own feeling towards the world, she must have been pretty well able to gauge those of the world towards herself; and perhaps she reflected that it is the ordinary lot of people to have no friends if they themselves care for nobody.
Well, meanwhile Becky was the greatest comfort and convenience to her, and she gave her a couple of new gowns, and an old necklace and shawl, and showed her friendship by abusing all her intimate acquaintances to her new confidante (than which there can't be a more touching proof of regard), and meditated vaguely some great future benefit--to marry her perhaps to Clump, the apothecary, or to settle her in some advantageous way of life; or at any rate, to send her back to Queen's Crawley when she had done with her, and the full London season had begun.
When Miss Crawley was convalescent and descended to the drawing-room, Becky sang to her, and otherwise amused her; when she was well enough to drive out, Becky accompanied her.
