How do other characters view Romeo?

They study and work

In general other characters see Juliet as a child, even though she certainly is old enough to be married. Tybalt wants to protect her as his cousin, Romeo is in love with her and wants to (and does) marry her. Romeo is seen as an enemy of Juliet's family, especially in the eyes of Tybalt. Tybalt is like a "rabblerouser" - Juliet does not think much about him until his death and then she is devastated. Romeo wants not to fight with him - the Prince has forbidden it - but ultimately he is forced into a confrontation because of Tybalt's killing of Mercutio.
