Good Purdy-poem by the way. The ironic repetition of the phrase "sensitive man" has a sort of Buk-ring to it... I enjoyed reading the Purdy-letters. Seems to me Buk lets down his tough-guy guard there a bit. I remember Purdy praising Buk's poem "The Shower" there.
Repetition is effective in many Bukowski poems. Seems to help focus the mind of the (this) reader. Here's an excerpt of a Lorca poem using similar approach. Can't vouch for the accuracy of the translation, etc. And I first heard it declaimed in a recent movie on the death of Lorca.
At five in the afternoon.
It was exactly five in the afternoon.
A boy brought the white sheet
at five in the afternoon.
A frail of lime ready prepared
at five in the afternoon.
The rest was death, and death alone.
The wind carried away the cottonwool
at five in the afternon.
And the oxide scatttered crystal and nickel
at five in the afternoon.
Now the dove and the leopard wrestle
at five in the afternoon.
And a thigh with a desolate horn
at five in the afternoon.
The bass-string struck up
at five in the afternoon.
Arsenic bells and smoke
at five in the afternoon.
Groups of silence in the corner
at five in the afternoon.
And the bull alone exultant!
