Romeo, Mercutio, the Nurse, and PeterSomewhere on the Streets of Verona
Tis no less, I tell you, for the bawdy hand of the dial is now upon the prick of noon.
Out upon you! What a man are you? (Line 116)
Mercutio is rudely insulting the Nurse, without context and not caring about her feelings. (Violence)
One, Gentlewoman, that God hath made him, himself to mar. (Line 117)
By my troth, It is well said...(Line 118)
The idea that you can say whatever you want contributes probably contributes to why the Capulets and Montagues are in a feud. They don't know where to draw the line and stop saying offensive things.
This relates to the motif of Conflict, because it is seen so much throughout scenes like this one, where petty arguments turn into brutal insults. Even Romeo thinks that Mercutio's insults are a bit crude/harsh.
Shakespeare is demonstrating that Conflict is everwhere, and can easily be avoided through Mercutio. This is seen, because all of the words that he said coul've been avoided, which would've prevented the conflict between the Nurse and him.
