It's hard to really know the Hill family. Their secrets are brushed over with a broad smile and ridicule nullifies even the most serious of discussions.  In this family even the unique aria of the soul is stamped out.   No one can be gay.  No one can be black.  No one can be fully human.  Assimilating in an all white suburban community, the Hills live on a dead end cul-de-sac of cookie cutter houses and sugary sweet smiles and no real life. The Hill family has become just like the neighbors they complain about.  As one character puts it, in this family, "everybody is dead.  You step over their dead bodies in the living room and talk to ghosts in the chairs."
