Describe the character/personality of Mercutio and what appears to be both his goal in life and his function in the play.
I would say that Mercutio's main character traits (or the things that best represent his personality) are his gift for talking and his happy demeanor. Mercutio seems like he would be a really fun guy to hang out with.
In terms of his function in the play, I would say that it is to be a fun guy who is sort of in contrast to Romeo's more romantic and brooding nature. Mercutio just wants to have fun, maybe hook up with a girl or two while Romeo wants to be deeply in love.
