In other fairy tales featuring the ball, she was driven from home by the persecutions of her father, usually because he wished to marry her.

Into the Woods, a musical with music and lyrics by Stephen Sondheim and book by James Lapine, includes Cinderella as one of the many fairy-tale characters in the plot.

It opened on Broadway in 1988 and has had many revivals.
Lifestyle and work habits partially determine how many calories we need to eat each day.
