Many scholars believe the hard headed and wise female characters in Shakespeare's plays may come from his own experience with his daughters. For example, his elder daughter Susanna, whose epitaph on the tome said she was "witty", was 13 years old when Shakespeare wrote Romeo and Juliet, in which Juliet was 13, too. In Romeo and Juliet's primary source, some Italian folktales, Juliet was depicted as a stupid young girl who disobeyed her father, eloped with another young man, then suffered from a much-deserved death. However, Shakespeare's father-daughter relationship in this story was rendered in a different light: Juliet's father was almost a tyrant in commanding her to marry someone that she didn't love; after Juliet died, she was not condemned but pitied. It was her father (and other relatives) who regretted and repented their old ways. Could Shakespeare's love to his daughter compel him to write Romeo and Juliet like this?
