It's a heartbreaking poem. One of the first things I think about when I think about pleasure is poetry. The pleasure of work's an ineffable thing. When a poem comes together, there's a kind of simultaneous locking into place and free fall, a little ripple that shudders, filled both with fear and ecstasy. It's like experiencing the change in season, when the cat suddenly perks up its ears or you catch the faint tinge of smoke.
Poetry is so ultimately crucial to the heart.
