He jests at scars that never felt a wound what does that remark mean?

My understanding of this line is as follows: Romeo of course is speaking to himself as he is hiding from his friend, Mercutio and Benvolio as they are leaving the Capulets' masked Ball where Romeo meets Juliet for the first time. (Romeo is planning to return to the House of Capulet to see Juliet again which is why he is avoiding Mercutio and Benvolio.) Prior to attending the party and seeing Juliette, Romeo had a crush on Rosaline and had been lamenting this frustrated love earlier in the play. Mercutio is calling out trying to locate Romeo and is teasing Romeo about his crush on Rosaline. Romeo responds basically saying, "ah, I'm over her (Roseline). I was never really in love with her anyway now that I've seen Juliet so your jokes are falling flat 'cause all previous attractions have disappeared after seeing Juliet.

That's right, isn't it Mr. Holbrook? (My high school English Literature teacher)

ha this guys a moron^ "mr.holbrook" would be very dissapointed kidd.

he can't even spell Juliet right. who the hell is roxanne? i do believe it's rosaline.

mind you im a freshman. yah kid you need to hit the books >.<

haha i agree with you this kid doesn't know how to spell but i fixed it for u your welcome.

Well, I don't think either of these people have actually answered your question, so let me see if I can... The quote "He jests at scars that never felt a wound," implies that it is easy for someone (Mercutio) to joke at scars if he has never been cut. Meaning, that Mercutio doesn't know what he is talking about when he speak of love, because he has never felt it according to Romeo
