where I killed a lot of Vietnamese gentlemen
a few ladies too
and I couldn't stand the pain
and got a habit out of fear
I've gone through rehab and I'm clean
but I got no place to sleep
and I don't know what to do
with myself right now
I'm sorry buddy, I didn't mean to bug you
but it's cold in the alley
my heart's sick alone
and I'm clean, but my life's a mess
Third Avenue
and E. Houston Street
on the corner traffic island under a red light
wiping your windshield with a dirty rag

 Allen Ginsberg  lived his later and final years in an apartment located on Manhattan’s East Village which is within close proximity of Houston Street. It is possible then, that this poem might have been inspired by a similar real life encounter.
