Baudelaire's L'Héautontimorouménos was long seen to be a sexual sadomasochistic poem, it is now generally accepted that the poem is about writing poetry.
These people you used to see every day, friends or acquaintances, after a while they become as distant as any stranger, people you suddenly recall late at night--you remember something they said or something silly that someone once did. For a few moments they completely occupy your mind; then you forget them again.
I like it to be quiet, and it usually occurs in the morning. There are three or four places in my house where I can write and I like to keep moving around. The moment I find myself falling into a necessary routine, I change it. I'd rather not accumulate superstitions.
