XIII
A.E. Housman

I lay me down and slumber
And every morn revive.
Whose is the night-long breathing
That keeps a man alive?

When I was off to dreamland
And left my limbs forgot,
Who stayed at home to mind them,
And breathed when I did not?

…

— I waste my time in talking,
No heed at all takes he,
My kind and foolish comrade
That breathes all night for me.
