Sometimes I think Grand Central is growing like a tree, pushing out new corridors and staircases like roots. There’s probably a long tunnel that nobody knows about feeling its way under the city right now, on its way to Times Square, and maybe another to Central Park. And maybe — because for so many people through the years Grand Central has been an exit, a way of escape — maybe that’s how the tunnel I got into... But I never told my psychiatrist friend about that idea.
