Strangeness Act one part one

The ideal of strange is seen a lot throughout the very first act. It even starts with characters referred as "the strange sisters" or "the weird sisters". This is huge as the entire foreshadowing is done by these "strange sisters". there are also the doubles that they speak of that are relatively strange. "when the battle is lost and won", while we realize that there is always a winner and a looser it seems odd to see it spoken in such a way. Also the fact that when the Strange Sisters proclaim that Macbeth shall be the Thane of Cawdor it makes it seem as if there are TWO at one time, thus creating a rivalry. I believe this rivalry will play out through the book from the death of the King (because Macbeth wants his spot) to the death of Macbeth
