A Characterization of Romeo's Friend
"True, I talk of dreams,Which are the children of an idle brain,Begot of nothing but vain fantasy,Which is as thin of substance as the air"
Queen Mab Speech
Mercutio rants to Romeo about the fairy tale of Queen Mab to show him that dreams mean nothing so that he will go to Lord Capulet.
After the Party
"Nay, I’ll conjure too!Romeo! Humours, madman, passion, lover!Appear thou in the likeness of a sigh!Speak but one rhyme, and I am satisfied.Cry but “Ay me!” Pronounce but “love” and “dove.”Speak to my gossip Venus one fair word"
Mercutio gets mad at Romeo because he wants to stay at the party to be with Juliet.
