Complicated Knee Joint

Complicated knee joint,
playing more to the left

and right than I would like.
A quiet movement sound now

a long way off; just vibrations
of aluminum cans going

through clockwork. As if
thigh and calf

were threaded with one
thin ligament affixed

to each bony end.
Of course now

having to be somewhere else;
the hospital, the supermarket,

with only "having walked
it a different way once,"

via your advice, abler and,
though being argumentative

and hesitant I, made it there.
To gravel-scraped up jar lids

on the sidewalk and
perfectly intact plain doughnuts

that looked paler, like they too might
smart against dropping pressure.
