Robinson Ellis was everything asked of a teacher,
several things unasked,
and one or two things you avoided asking entirely,
even after graduation.

But it was a lesson well taught:
if you asked Mr. Ellis about the Ibis,
you had better have brought receipts for the Ibis,
which would have proven desperately and irrecoverably Sisyphean,
when Ellis owned every receipt of the Ibis
and had receipts for those receipts to prove it. (ap·dt)
