Egon Friedell might disagree and say he was one of the greatest satirists in the world who said more in one short fairytale than some others said in a thick novel. But don't believe Egon Friedell.

[Charles Dickens] also had the stress of dealing with Hans Christian Andersen, whose projected two-week visit [to Dickens's new home at Gad's Hill] extended to five weeks. Andersen's eccentricities did not endear him to Georgina [Hogarth, Dickens's sister-in-law] and the children (Katey later remembered him as 'a boney bore who stayed on and on') but Catherine [Dickens's wife] was always kind to him and Andersen persuaded himself that Dickens must have modeled Agnes in Copperfield on her. Dickens also was unfailingly kind, comforting Andersen when he was distressed by a bad review, but confessed to [Angela] Burdett Coutts on 10 July [1857], 'We are suffering very much from Andersen' before going on to give her a hilarious account of Andersen's misadventures in a London cab.
