What's Up Doc?

In college
I called
all my PhD
teachers
"Doc"
a term
of endearment
and because
I knew
even then
I wouldn't
get much chance
to use
the moniker
often.
They all
tolerated it
to various
degrees
but
my calc prof
really got a bang
out of it
I don't recall
her name
probably because
I always
called her
"Doc"
and calculus
is some
fifteen years
in the rearview
but I remember
her clarity
and humor
in the classroom
and her eyeroll
and grin
whenever
I called her "Doc".
