That's the name of the game sir.

Yeh

it says enough.
a gem.

Well done. Strength in a single thread.

This reminded me of an old poem of mine from nearly 30 years ago when I was in my early 20's called
"Stock Room Blues". It starts out with a similar concept...

I've yet to do what I really wish
I've come home smelling like a fish
Scraping off windows covered with grime
Hardly makes my Summertime sublime
I don't live to work I work to live
More at night when girls are amative

Do you have the rest of the poem? It is very similar to this one.

Yes, it is posted in my library here.

line placement/ word order is a bit odd.
does he live at night or work at night?
maybe this is just me.
some contrast between day and night would clear it up, two or three more words.

like the feel, the simplicity. like it says, its all we need to know, not a word more
