shut up/ i don't know what this is / needs work

[crossinghouses]

The second storey above the grocers’
up some narrow, crumbling stone steps;
is where I ply my trade these days
I am the proprietor of losing (not lost)- things

Welcome - place a wager, anything goes
I play all or nothing or nothing.
not afraid of walking away with
nought; having come from none.

I have lost more than I dared to wager
and then some, gained more,
keeping up with this deadly roulette
I am the proprietor of losing (not lost)- things

We all start from nothing at all; toiling,
gambling for keeps, dying with none
I’d pawn my blood too;
it’s worth nothing I am told.
