Explanation:
- **Tragedy Degree: 2** - The story contains minimal tragic elements. While there are subtle hints of aging and nostalgic reflection on past youth, there's no profound tragedy or strong emotional setback present.
- **Comedy Degree: 4** - The story does not have strong comedic aspects, but it maintains a generally light-hearted and optimistic tone. The interactions between Evelyn and Lily bring a sense of warmth and mild joy, making it feel somewhat light-hearted. However, it doesn't reach a level of strong comedic impact or an extremely happy ending.
