### Explanation:

**Tragedy Degree: 7**
The story of Henry revisiting the abandoned factory where he spent much of his life is deeply poignant and evocative. It delves into themes of nostalgia, loss, and the passage of time, creating a strong emotional impact. The sense of his unfulfilled longing and the decayed state of a once-thriving place add to the tragic elements, although it doesn't reach the pinnacle of tragedy as there is a sense of acceptance and tribute in his actions.

**Comedy Degree: 2**
The story contains almost no comedic elements. There is a mention of laughter and camaraderie from the past, but these moments are overshadowed by the overall sense of sadness and loss. The story is primarily somber and reflective, without any significant light-hearted or joyful moments.
