Final answer:
Playing represents an imaginary world, while reality represents real-life events and circumstances.
Step-by-step explanation:
The difference between playing and reality for these boys is that playing represents a temporary and imaginary world, while reality represents the actual events and circumstances of their lives.
In the given examples, when Jack says, "I'm not going to play anymore," it suggests that he is no longer participating in an imaginary game or activity. This implies that the boys were engaged in pretend play or recreational activities.
On the other hand, reality refers to the world outside of their imagination, where real-life events and responsibilities exist. In the context of the examples, reality is represented by the actions and decisions of the boys, such as quitting a job or locking up a nursery.
