Quatrain occasioned by a "We Miss You!" Notice

To what do the dead subscribe?
what periodicity draws them?
what news do they seek? what tribe
of angelic beings awes them?

==========

Note scrawled on a form letter
that arrived today, addressed to my late father (sent by the subscription department of The Progressive, a left-wing magazine) ; the letter begins:

Dear Sam Israel:
We miss you, and I thought you might be missing us, too. . . .

My scrawled note reads:

Dear Progressive:

My father, Sam Israel, passed away in October of last year.  He loved your publication, and for that I thank you.  But you need send no further subscription reminders.  Sam Israel is now permanently unsubscribed.

Thanks!
David Israel
