A story of a girl who grumbled to her father

A girl grumbled to her father about her hard life. She didn't know what to do and wanted to give up. She felt tired of fighting and fighting. One problem had been overcome, but the other overcame her. Her father, a cook, took her into the kitchen. He poured water into three pans and set them to boil. On boil, he put some carrots in the first pan, some eggs in the second pan and coffee in the third pan. He watched for some minutes without saying anything.
