Fr. Laurence, Why?

For my online book club we read Romeo and Juliet, which my students are now reading as well. Once I get to Act 4, I want to just ask Friar Laurence why on earth he thought this plan with Juliet taking a sleeping drug would work. Why not tell her parents, Friar? Since she’s already consummated her marriage to Romeo, wouldn’t the Capulets and the Montagues have to make the best of things?

The Friar even tells Paris he doesn’t like the hasty marriage to Juliet. That’s a great start. Just tell the truth or if he’s such a coward, tell the parents they have to wait a certain amount of time after Tybalt’s death to marry. Then have them tell the truth. One of them would get the courage to.

I realize Shakespeare took the story from another source, a poem by Arthur Brooke and he saw that it had a lot of powerful elements, but there are some glaring mistakes in the plot.
