i do not think that this aspect of rowan 's life is any concern of ours , except to note that her taste seemed similar to that of mary beth mayfair , and that such a pattern of random and limited contacts reinforces the idea that rowan is a loner , and a mystery to everyone who knows her that she does not talk about herself to these bed partners is obvious perhaps she can not talk about herself to anyone , and this may be one key to understanding her compulsions and ambitions .
