before her as the lights start to come down. She looks around at all the
walls and ceilings and suddenly, despite herself, while the children call
below, a great heaving thing rises in her and she puts her fist to her mouth
to stifle it, takes a final desperate look, pulls her coat about her, pats her
hat, and goes out. The lights dim down. The door opens and she comes
back in, grabs her plant, and goes out for the last time.*
