But she did not accept it , and she answered him at once : `` No , Burton , so long as father lives I must stay with him , and you will be happier without than with me . We are not at all alike . But I thank you for asking me all the same , and now it is time for me to go , if I take the four o'clock train . Father will be expecting me . '' Burton went with her to the train , and saw her into the car , and bought her _ Harper 's Monthly _ , and bade her good-by , and then , in passing out , met and lifted his hat to the Misses Grey , Lucy and Geraldine , who had been visiting in Boston , and were returning to Allington . This encounter drove his sister from his mind , and made him think of his aunt 's injunction to marry one of the Greys .
