Mr. Micawber's appearances in David Copperfield
The Micawbers as examples of survival
From David Copperfield Chapter 13 : The Sequel Of My Resolution
But my standing possessed of only three-halfpence in the world (and I am sure I wonder how they came to be left in my pocket on a Saturday night!) troubled me none the less because I went on. I began to picture to myself, as a scrap of newspaper intelligence, my being found dead in a day or two, under some hedge; and I trudged on miserably, though as fast as I could, until I happened to pass a little shop, where it was written up that ladies' and gentlemen's wardrobes were bought, and that the best price was given for rags, bones, and kitchen-stuff. The master of this shop was sitting at the door in his shirt-sleeves, smoking; and as there were a great many coats and pairs of trousers dangling from the low ceiling, and only two feeble candles burning inside to show what they were, I fancied that he looked like a man of a revengeful disposition, who had hung all his enemies, and was enjoying himself.
My late experiences with Mr. and Mrs. Micawber suggested to me that here might be a means of keeping off the wolf for a little while. I went up the next by-street, took off my waistcoat, rolled it neatly under my arm, and came back to the shop door.
