At the start of the play , the chorus tells us a little speech of what is going to happen in the play .  The line ” A pair of star-crossed lovers take their life” tells us that the 2 lovers (Romeo and Juliet) take their lives away . It is a bit weird to tell us the story line at the start but then for the whole play we want to find out how and why they kill themselves , so we stay tuned and listen till the end because in this story if you miss a bit of the play , you will not understand what’s going on.
