Sometimes they are all Up the Down Staircase:
Please use the computer we never gave you
Respond to the directive we never sent
And send again the grades you sent last month

You have thirty students in your night class
The adjunct next to you has only six
Well, no, you don’t get any more pay than him
          I mean “than he”
We’re miffed that you even asked about that

Your roof is leaking only because it’s raining
And you’re overdue for your pervert training

The years add up
But you never truly forget  
Just cover it up
with leaves, some brush
an old sheet or blanket
A drive
a new route around
Sometimes an old box in a closet
or under a bed work fine
to hide the time

until the winds of seasons change
bare it all again

..and there's never any tissues around
