Die Gänsemagd
When the hero of the Child ballad "The Lord of Lorn and the False Steward" is forced to trade places with an impostor and swear never to reveal the truth to anyone, he tells his story to a horse while he knows that the heroine is eavesdropping. In the similar fairy tale "The Goose Girl", the princess pours out her story to an iron stove, but not knowing that the king is listening.
