The Curse of Courtesy

Arriving five minutes early
to the four o'clock class
You hold the door for one person,
and end up holding that door
for all 275 students
streaming out of the lecture hall,
plus one professor,
and one student-aide.
Four thank-you's, one nod,
and seven minutes after
the moment I pulled that
damn door open,
I decided that next time
I'm going in through the out
