Ending

The piece might end this way: Everyone's trudging, contentedly, back to the Oak Floors, having just finished a big number singing its virtues, and plentiful doubts. One by one, the characters veer off, with a wave to those remaining, and to audience. Patty is the last one.
She looks at the door (twice before she'd forgotten her key), at the audience. A pause. And it opens. She disappears inside, good-bye. To black.
