where I can’t say buttercup, bobolink,
sugarduck, pumpkin, love ribbon, locket,
valentine, summergirl, funnygirl and all
those nonsense things one says in bed.”

“The secret thoughts of a man run over all things, holy, profane, clean, obscene, grave, and light, without shame or blame.”

“without luggage or defenses,
giving up my car keys and my cash,
keeping only a pack of Salem cigarettes
the way a child holds on to a toy.
I signed myself in where a stranger
puts the inked-in X’s”
