Based on the provided story, I will evaluate the Tragedy Degree and Comedy Degree according to the given criteria.

### Tragedy Degree:

- The story includes some setbacks and struggles, such as Mac's exhaustion and the challenges of parenting, which can be emotionally taxing.
- However, there are no profoundly tragic elements or severe emotional impacts.

### Comedy Degree:

- The story maintains a sense of warmth and camaraderie, and ends on a hopeful note with the suggestion of a playdate and a strong bond between friends.
- There are light-hearted elements but not significantly comedic or strongly emotionally delightful moments.

Given these considerations, the scoring is as follows:

- **Tragedy Degree**: Moderate tragic plots with some emotional setbacks.
- **Comedy Degree**: The story has some comedic plots and is relatively light-hearted.
