Final answer:
Cal wasn't upset about Arnold wanting the money back; he felt bad about something else. Without additional context, we can't definitively say what this 'something else' is.
Step-by-step explanation:
The fact that Cal didn't feel bad about Arnold Bacon wanting the money back indicates that the main source of his guilt originated from elsewhere. From this context, we can assume that Cal felt bad not because of the money, but because of some other, possibly deeper, issue. Unfortunately, without the context of a specific text or story, it's impossible to accurately determine what exactly made Cal feel bad. To fully understand Cal's feelings, more information about the narrative source or context is needed.
