You could also see this as a talking point,which is probably what the creator was after. The nudity is not really the main subject here more the statement of the class.I see it as a take from it what you will short film and I see it more as a statement of youth. It's a typical "We are the youth of today" statement...they want to be different. Once the teacher takes her clothes off they're not different...so once again they change by getting dressed and pushing her out on a limb when the door opens. It's still relevant in all kinds of ways as it asks you "why are they naked ?" If plain nudity is something that the watcher doesn't understand they will see it differently to someone who is naked everyday. It's not a classic but can start some interesting conversations 🙂
