Opera and music critics would also frequently leave performances before they were over, a fact that would be noted in their reviews (e.g., "Left prior to Brunnhilde's immolation," etc). At some point, they determined that opera reviews appearing overnight were not a matter of dire consequence...
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
