‘The Rattrap’ deals with human emotions. These emotions, at times, give rise to unexpected behaviour. One of the most important unexpected behaviour is of the crofter towards the peddler. When the peddler asked him for shelter in the night, he welcomed him and gave him food, tobacco and company. The crofter bestowed so much confidence in the peddler that he even showed him the thirty kronor that he had saved. In another instance, the peddler was first persuaded by ironmaster to come to his home and when he realised his mistake, he got furious and threatened to call the sheriff. Yet another and the most unexpected reaction is that of Edla Willmansson. When the peddler was asked to leave immediately, Edla closed the door and insisted that the tramp stay at their home for Christmas.
She showed extraordinary kindness to him. The most unexpected behaviour was that of the peddler. Edla’s kindness brought out the essential goodness in him and he left the home leaving behind a gift for Edla along with the money he had stolen.
