From Shmoop Literature on Romeo and Juliet http://www.shmoop.com/events/literature/william-shakespeare/romeo-and-juliet.html Summary We meet our hero, Romeo, after a duel between the young men of two enemy families of Verona: the Montagues and the Capulets. Romeo Mongtague is pining away for Rosaline, a girl we never see. Juliet Capulet, age thirteen, has just heard that Paris, Verona's attractive young bachelor, would like to marry her. The two will meet that night at a masquerade ball at the Capulets' house. Romeo and his friends have decided to crash the Capulet ball - in costume - because Rosaline is on the guest list. Romeo meets Juliet there instead, and they fall madly in love. Afterwards, they discover they are members of rival families, but they are still in love. Romeo stays after the party under Juliet's balcony, and the two use this romantic meeting to plan their marriage. Hasty, but genuine.
Civil brawls, born of an airy word, seem to happen with little provocation. People assume that what the Capulets do, they do to slight the Montagues and vice versa. Thus Tybalt assumes that Romeo has crashed the party just to "fleer and jest" at the Capulets. He continues to act on that assumption even after Capulet points out to him that Romeo is doing nothing of the kind. Paris also assumes that Romeo must be up to no good in visiting Juliet's tomb, just because he's a Montague. Both of these groundless assumptions lead to fighting and death for those doing the assuming.
he thinks he is there to vandalize the tomb and to mess with the dead bodies
