The bus is an old machine, the driver has lines over his brows, the old trend of biking comes full circle, and Doris is no longer the young buck she once was.
Then, instead of sitting in the most convenient seat, she chooses one in the back, a quiet spot that contrasts against her former busy, noisy life of working, gym, and parties.
