Constant Themes of Romeo and Juliet Question

Dr. MB encouraged us to think about why this iconic story has stuck for centuries as we read the text. After reflecting on the text (and being thankful it was over) I was left considering three major themes that draw in the reader.

Ultimately these draw on many of the complexities of human nature and pull at many of the things that motivate us in our current lives.
