"There was, she thought, enough sadness in the house, maybe even more than she realized.  She would try as best she could not to add to it.  Her mother and Rose could not be fooled, she was sure, but there seemed to her an even greater reason why there should be no tears before her departure.  They would not be needed.  What she would need to do in the days before she left and on the morning of her departure was smile, so that they would remember her smiling."
-Brooklyn by Colm Toibin
