From the opening speech of the bard, we know that Romeo and Juliet will "take their lives." It is difficult to keep this dark, looming destruction on our minds as we see a youthful passion blossom. Romeo and Juliet both show us so much light and life, it is difficult to see a dark end to in their future. I think that is one of Shakespeare's great achievements with this work. We, the readers, already know what is going to happen, but we end up still being surprised in the end. We want Romeo and Juliet to ride off into the sunset and live happily ever after. They come so close to happiness time and time again that we find ourselves willing them to that end rather than the one we know is coming.
