Sampson and Gregory (Capulet servants) initiate a fight with abraham (Montague servant). Then Lord Capulet and Montague begin to fight. The fight between the two adversaries ended when the prince threated to kill them.
Mercutio and Romeo and Benvolio
Rome is lovesick with the thought that Rosaline doesn't love him. Mercutio and Benvolio make fun of him as he is acting very childish.
You fool. Your dream of Rosaline means nothing.
Romeo come on. There are many fish in the see.
Romeo first sees Juliet and forgets about Rosaline as he is overwhelmed by Juliet's beauty. Romeo approaches Juliet by asking for a kiss. Instead, they kiss using their hands (palm to palm). They are both attracted to each other. They flirt and exchange a kiss.
