Poet and teacher of mine from a long way back, Peter Sears, taught me about a thing called poetry by corruption, whereby you, the writer, take a poem that you like and just simply and with impunity steal things from it, or, steal it wholesale except for some words or phrases you’ve blanked out from the original and then replaced with your own stuff. It’s only legal because it’s a good exercise to teach us about the choices poets make and it’s a way to pay homage and attention to a poem we love. The only rule: don’t try this at home unless you’re willing to give credit to the original poem. The following is a corruption of one of my favorites by William Stafford.
Why I Am Happy
(from William Stafford)
Now has come, an easy time, I am done
grading sophomore essays, and there is
a lake somewhere so blue and so far
no more student work can find me.
A wind comes, saying, you’re not there yet.
In a few more days will come student
notebooks and portfolios and senior
final exams into my attention. For now,
a lull, unusual, like the one
I hear every summer, when I, too,
laugh and cry for every turn of the world.
Grading goes on and on
but that lake goes on and on even farther;
and I know where it is.
