Hally is only linked to his parents biologically. Qualify this statement.

Hally is linked to his parents biologically by blood and family belief systems. Hally readily admits that the happiest moments in his unhappy childhood have been spent with Sam and Willie, usually hiding out in the room they shared at the boarding house his mother used to run. However, racism is deep-seated in his country and his family, and over time, Hally has unwittingly absorbed some of his father's bigoted ideas. During an emotional afternoon in his mother's deserted café, he unleashes some of those thoughts on Sam and Willie in the ugliest manner possible, threatening to destroy what are possibly the most meaningful relationships in his life.
