(I don't know what I mean)

(I don't know) what it means when it comes all covered in conviction.
crashing down onto my back porch, overdosed and overdue. telling me he's got no
home. and no kitchen tables or literature.
and I don't think he's been dreaming.

what does it mean when he comes close
hands me a heart and I says
"if you break it, I promise no to tell."
