Read the excerpt from Act III, scene i of Romeo and Juliet.
Mercutio: No, ’tis not so deep as a well, nor so wide as a church door; but ’tis enough, ’twill serve: ask for me to-morrow, and you shall find me a grave man. I am peppered, I warrant, for this world. A plague o’ both your houses! ’Zounds, a dog, a rat, a mouse, a cat, to scratch a man to death! a braggart, a rogue, a villain, that fights by the book of arithmetic! Why the devil came you between us? I was hurt under your arm.
What is foreshadowed by Mercutio’s statement that tomorrow "you shall find me a grave man”?
