Scene Summary: 

Two men from the house of Capulet — Gregory and Sampson — pick a fight with a few Montague men. Benvolio, a Montague man, tries to break it up, but his efforts aren’t exactly successful when Tybalt, a feisty Capulet, arrives to fuel the fire. The fight finally breaks up upon the arrival of the prince of Verona. Once the fight has broken up, Montague and Lady Montague ask about their son Romeo. Benvolio tells them that he has seen Romeo moping around in a bit of a stupor. After they leave, Romeo arrives to tell Benvolio why he’s really in a funk: he’s in love with a woman who does not love him back.
