This beautiful tale teach children not to be too naive in life in order not to get into trouble. Simpleton duck trusted to the sly fox and hardly pay for this by her own life. Thanks to her friend collie dog the story was ended with happy end. Quote: "Madam, I beg you not to trouble yourself with a bag; I will provide oats. But before you commence your tedious sitting, I intend to give you a treat. Let՚s have a dinner-party all to ourselves! “May I ask you to bring up some herbs from the farm-garden to make a savoury omelette? Sage and thyme, and mint and two onions, and some parsley. I will provide the lard for the stuff— lard for the omelette,” said the hospitable gentleman with sandy whiskers. Jemima Puddle-duck was a simpleton: not even the mention of sage and onions made her suspicious." Beatrix Potter, "The Tale Of Jemima Puddle-Duck",
