Tybalt is trying to start a sword fight with Romeo.
Explanation:
Tybalt is looking for Romeo to fight him for attending the Capulet ball uninvited. Because the Capulets and Montagues are in a family feud, Romeo “crashing” the party is disrespectful and forbidden. ... Because of this, Romeo doesn't want to fight Tybalt, but he can't tell him why.
