"I happened to be at Cambridge. I was sent there by the [US] government on a government grant. And I'd read some of Ted's poems in this magazine and I was very impressed and I wanted to meet him. I went to this little celebration and that's actually where we met. Then we saw a great deal of each other. Ted came back to Cambridge and suddenly we found ourselves getting married a few months later... We kept writing poems to each other. Then it just grew out of that, I guess, a feeling that we both were writing so much and having such a fine time doing it, we decided that this should keep on."
