"One may choose to forget, but one may not be able to accomplish it. To forget or to remember is not in one's own power."
"That is what fickle people say. But what one feels one remembers."

"Are you?" she says, at length, after a long silence.
"I think so, Mona. There is one thing I shall never get."
"Many things, I dare say," she says, nervously, turning from him.
"Why do you speak of people dropping out of your life?"
"Because, of course, you will, you must. Your world is not mine."
