the control switch

"At first, all goes well, but after two or three months a pattern begins to emerge, and Grace understands that she’s trapped in a machine. Trause wants her and he doesn’t want her. He knows he should give her up, but he can’t give her up. He vanishes and reappears, withdraws and comes back, and each time he calls for her, she goes flying into his arms. He loves her for a day or a week or a month, and then his doubts return and he withdraws again. The machine goes off and on, off and on… and Grace isn’t allowed near the control switch. There’s nothing she can do to change the pattern."

Oracle night, Paul Auster
