First and Last Days (A Little Prayer, revised, new title)

[busker]

A Little Prayer
“I’ll wait for Jesus, if he’ll wait for me” (graffiti)

I’m a broken old man
adrift on a sea of night sweats …. Maybe enjamb with a break at ‘sea’ 
and misunderstood faces,
my body a waterlogged raft …. Great image 
too stubborn to sink decently 
and let the deep devour me at last. …. I, my…don’t need the ‘me’. Also, feels stretched. Maybe ‘devour it’, which concludes the raft metaphor?

If it’s all the same to you,
my life was an absurd one.
Who knew absurdity
could become so fragile?
Now it creaks, exudes foul gases, …. ‘Gas’ rather than ‘foul gases’ should do it
disgusts the young
who see the pale rider 
behind my eyes … a nice swerve from the corporeal to the not so much 
and turn away, angels
who glance towards the damned,
sometimes with pity,
sometimes with surprise.  …nicely done 

I know there’s a joke
at the end of this empty math.
I just hope I can laugh
when the punchline comes. …. The last 2 lines are weaker than the rest of the poem. Can’t suggest anything at the moment, but 

Nice one.  Can be made better
