A childhood friend of mine sent me a copy of John Updike's
final volume of poems "Endpoint." He wants my help translating
it into German.  I've been practicing reading poetry. 

It hadn't previously occurred to me to consider,
on the one hand, how the constraints of rhyme, rhythm and
versification, especially in a poem as strictly structured
as the sonnet, impinge on the poem's meaning.
And on the other hand, how much that meaning is enhanced,
enlarged and amplified, by the discipline required to express
it in so strict a form. I conclude that I was insufficiently
appreciative of your windows poem.
