The mathematics of infinity

He had run around a lot when he was younger,
had been pretty good athlete
and footballer
later the cool uncle –
the popular one, who always seemed younger
bought us ice creams and decent presents.

and approval we wanted.
He always made time, and always brought enthusiasm.

constant division of self
to end in multiplication of assistance
of shuffling corridors
pureed food
call buttons
assisted showering, bedpans
and square root of what once was.
