About a decade ago I was at a museum in Odense, Denmark. I vaguely remember a comical story about him and Charles Dickens. In that Andersen would regularly visit Dickens and stay with him and his family. The gist was that Dickens found this to be quite irritating, as he was not enthused by Andersen's company, finding him to be much too emotional and having "strange" Danish customs.

Curious what a strange Danish custom entails
