Why should Romeo and Juliet be taught?

Please fix my Romeo and Juliet introduction?

• Is it on topic? The topic is ''There are times when secret must be told''. Any grammar mistakes? Secrets have been included in literature for centuries. Literary works often teach valuable moral lessons. Whether they are the simplest children's books or Shakespearean tragedy, lifelong lessons are taught. In the beginning of the story, Romeo and Juliet shows that secrets should be kept for the well being of others. However, throughout the story, the well kept secrets turn out harmful for two families. Thank you.

• Answer:

  I don't think you need a comma after however but it's perfect :) very well worded.
