Cinderella

Straight back, chin out: you study her every move, ready to remind her of her rightful place. You know what she thinks of you. She looks at you and does not understand how you came to power She will never know what it means to live as if the world belonged to her, to craftily pull the strings: a daughter to be married to a tycoon, another one the leader of a company and she, your stepdaughter, relegated in a menial job. For a thousand of her efforts, you only need to move a finger or whisper a word in the right ear.
Your social status is your main accomplishment, being in control is your weapon. You do not care about her judgments but focus on your efforts and picture the triumphs ahead.
