Mr. Micawber is Comic Relief – in the grimmest part of the novel, when David has been cast out by his stepfather and is basically roaming the streets of London, in steps Mr. Micawber to lighten the tone of the novel a bit. David meets Mr. Micawber when he first moves to London to work at Murdstone and Grinby. Mr. Quinion finds David a place to live by renting him a room in Mr. Micawber's house. David and Mr. Micawber become instant friends, primarily because Mr. Micawber cannot seem to remember that David is only ten years old: he constantly brings his financial troubles to David, as though David could give him sound advice or assistance as a ten-year old.
