I think you're right; actually, I'm sure you are. I just found the resolution of the story a bit over-subtle. Maybe it was Mulder playing the piano, of which we've never had a hint in canon (have we?). It's described as "rough" and "unpolished," but I think it would realistically sound bad enough to screw up the mood she's trying to achieve.

No matter. It's a nice story. Now I'll just burrow underground with my neighbor the groundhog and wait out this vicious winter. The descriptions of sticky summer heat were quite refreshing!
