In other words, it's as if it's like a symbol of the repression. We don't want to admit to it. But in spite of our attempting to stay repressed about it, blood will out, murder will out, as Chaucer says in one of his tales.
Det symboliserer undertrykkelsen, vi vil ikke innrømme det men i våre forsøk på å undertrykke det kommer blod og drap ut, som Chaucer sa i en av historiene.
