Read the excerpt from act 1, scene 3, of Julius Caesar. CASSIUS. Am I not stayed for? Tell me.

CINNA. Yes, you are.
O Cassius, if you could
But win the noble Brutus to our party—

CASSIUS. Be you content. Good Cinna, take this paper
And look you lay it in the praetor’s chair,
Where Brutus may but find it. And throw this
In at his window. Set this up with wax
Upon old Brutus’ statue. All this done,
Repair to Pompey’s Porch, where you shall find us.
Is Decius Brutus and Trebonius there?

CINNA. All but Metellus Cimber, and he’s gone
To seek you at your house. Well, I will hie,
And so bestow these papers as you bade me.

CASSIUS. That done, repair to Pompey’s Theatre.
