There's a double meaning in that

I am attempting to fill the bath using the shower. It's taking quite a while, and I kind of feel it should be a metaphor for or statement of something.

Mostly what it is a statement of is "I should put the hot water tank on earlier if I want a bath."

Nevertheless, I can't help feeling that it's the kind of thing that, if used in a story, would hold deep and meaningful significance.

*waits*

Nope. Still just boring...
