The Shoemaker's Apron

There was once a woman who had two girls. One was her own daughter, the other a stepchild. Holena, her own daughter, she loved dearly, but she couldn't bear even the sight of Marushka, the stepchild. This was because Marushka was so much prettier than Holena. Marushka, the dear child, didn't know how pretty she was and so she never understood why, whenever she stood beside Holena, the stepmother frowned so crossly.
