Sonnet: Rent Control Cage

That lo! a landlord letter these walls shake
the flimsy wood the rent control cage
where in a blink the generations age
then pressure antecedent lives unmake
the piled sand upon the joy and ache
a blend judged right accorded retro sage
insight that hardly shields against the rage
the roiling real estate the money quake
as upstairs in the vacancy current
of air or footprint of a cat or ghost
the shadow doubt of who or what to come
whose onset would evoke relieved welcome
though minutes creak for those affected most
the one who sent the one awaiting rent
