These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Cargo Ship: In some productions the wall is performed by a woman, sometimes during the love songs between Matt and Luisa the wall might stare sadly at Matt with jealousy.
Family-Unfriendly Aesop: The play delivers the hard but true moral that sometimes you can never appreciate what you have until you lost it. Matt realized living on the edge in excitement and adventure is only fun until you fall off that edge. Luisa can't understand what it feels like to have someone mend her heart until someone breaks it first.
"Funny Aneurysm" Moment: The song "Try to Remember" after 9/11. It was actually sung at many memorial events, including at Ground Zero in December of 2001, just three months after the attacks.
