Tales of Folk and Fairies by Katharine Pyle

Ashipattle had one sister, and she was very good and kind to him. In return for her kindness he told her long stories of trolls and giants and heroes and brave deeds, and as long as he would tell she would sit and listen. But his brothers could not stand his stories, and used to throw clods at him to make him be quiet. They were angry because Ashipattle was always the hero of his own stories, and in his tales there was nothing he dared not do.
