I wanted to make a simple movie with dialogue as this coding is a good example of the broadcasting of messages between two distinct pieces of code, those code pieces being the code for the cat and the bear. This demonstrates to us that a parallel exists between two characters interacting by broadcasting messages to each other in real life as in the movie(by their speech), in the same way as the underlying two code pieces of the cat and the bear object are simultaneously broadcasting messages between each other.
